Engine Diagnostic Service

Check engine light indicators have several meanings, the problem could be serious like a malfunctioning catalytic converter or simple like a misplaced cap.

How much does a Engine Diagnostic cost?

It depends on the type of car you drive and the auto repair shop you go to. Our mechanics are mobile, which means they don't have the overhead that repair shops have. They provide you convenience by coming to your home or office.

How this system works:

The check engine light indicator location and color will vary by vehicle, but in most cases it is a dashboard warning light that has an engine-like shape and a yellow or orange color. This indicator is part of the onboard diagnostics system and highlights an issue with your emissions system.

An check engine light indicator will either stay solid or blink.

  • If the indicator is blinking, the situation is usually serious, such as a severe misfiring of the engine. This would allow unburned fuel to dump into the exhaust system, pushing the temperature of your catalytic converter to the breaking point. Slow the car down, find a safe place to stop, and request a mechanic to perform a diagnosis.
  • A steady light on the other hand is not an emergency situation. You can continue driving, but you should contact Instamek and schedule an appointment with a mechanic as soon as possible.

Common reasons for this to happen:

While an check engine light symbol can light up for a number of reasons, typically it is due to one of the following issues:

  • Damaged or loose gas cap. This might seem like a trivial reason for your check engine light to turn on but it happens a lot. Your gas cap acts as the seal for your fuel system and it helps maintain the pressure in your fuel tank. A loose or damaged cap can reduce your gas mileage and increase emissions from your car.

    When the engine light turns on, pull over and inspect your gas cap. If it is loose, a quick tightening should solve the problem. If it is damaged, head to your local auto parts store for a new one. Once you have fixed the issue, continue driving to see if the check engine light turns off. If the light stays on, schedule an appointment with a mechanic for engine diagnostic

  • Faulty oxygen sensor. An oxygen sensor monitors the exhaust for unburned oxygen, which indicates engine efficacy and the proper air-to-fuel ratio. If you have a faulty sensor, it will not provide the correct data to the onboard computer. The majority of vehicles have two to four sensors. The OBD II code will tell the mechanic which one is giving a reading that is outside of its parameters.

    Deterioration of the precious metals inside the oxygen sensor affects the sensors’ ability to give an accurate reading. If you put off getting an oxygen sensor replaced, it will eventually damage your catalytic converter, which can be very costly to replace. Your best bet is to call a mechanic and get a proper diagnosis.

  • Failing catalytic converter. A catalytic converter helps reduce emissions in the exhaust gases. It converts the carbon monoxide and other harmful gases into less harmful emissions. A failing converter will negatively affect your gas mileage and when the damage becomes severe enough, your vehicle won’t go any faster when you push down harder on the gas pedal. This is a significant point where you will need to get engine diagnostic.

    In most cases, a catalytic converter will not fail if you properly maintain your car. A failing converter can be the result of a faulty oxygen sensor that has not been replaced or any other engine efficacy issue. A broken catalytic converter will eventually bring your car to a complete stop. Before that, your gas mileage will be horrid, the car will not run smoothly, and the car will not pass an emissions test. A damaged converter should be replaced immediately.

  • Faulty mass airflow sensor This part directs the computer in your vehicle to add the correct amount of fuel based on the air that is coming through the engine. When a mass airflow sensor starts to fail, the car will stall, it will idle poorly, the emissions will go up, and your gas mileage will go down. An air filter that has never been replaced or improperly installed can sometimes be the culprit when it comes to a faulty mass airflow sensor. Have your air filter checked and replaced on a yearly basis. While it is possible to drive for months with a malfunctioning mass airflow sensor, it’s not a good idea. Your gas mileage will drop and the car will start stalling frequently. It is best to call a mechanic and have the sensor diagnosed and replaced if necessary and hence have the proper engine diagnostic done.
  • Bad spark plugs and wires. A spark plug provides the gap for the spark that causes combustion in the engine. Spark plugs naturally deteriorate over time: while newer cars can go 160,000 km on a set of plugs, older vehicles, especially those built before 1996, require new plugs roughly every 75,000 kilometers. If spark plugs are your issue, your car may stall, have difficulty starting in the morning, have high fuel consumption or have trouble accelerating. Get them replaced immediately; a mechanic can make quick work of the job and new plugs in most cases are very affordable.

What to expect during and Engine Diagnostic:

One of our certified mobile mechanics will arrive at your specified location to identify the source and cause of the illuminated Engine Diagnostic Light, and then investigate and inspect other system components as certain problems are identified.

After the inspection, the mechanic will provide a detailed report that describes the diagnosis, along with the scope and cost of the necessary repairs.

How it's done:

When the Engine Diagnostic Indicator is on, your car’s monitoring system will have "fault codes" that indicate the nature of the problem. Your car may have one or more problems and hence there can be multiple codes.

The mechanic will read the codes using a scanner, interpret the codes, and provide a diagnosis. If you approve the repair estimate, they will replace the faulty part(s), clear the memory of any fault codes, turn the Engine Diagnostic Indicator off, and let you drive the car for a few days to see if the light comes back on or not.

Please note: It may take several days of driving the car for the monitoring system to verify that the repair has fixed all the problems. If the monitoring system fails any of its internal tests, it will turn the light back on. This means that the car has more problems that were not evident during the first evaluation. The mechanic will have to perform further diagnosis and create new repair estimates for resolving the problems found. Although it’s rare, multiple visits may be required to diagnose and resolve the stubborn check engine light issues.

How important is this service?

A blinking Check Engine Light shows a critical issue, whereas a solid light means a non-emergency situation. If the problem is not a loose gas cap, then a certified mechanic needs to determine the real source of the problem immediately.

Mohamed (Moe) worked on our car. We had another issue the day after he replaced some gaskets in our engine. He made the drive from Port Coquitlam to Vancouver on his day off to help get our car running again. He was very kind, transparent, and professional throughout the process.

Alexey came to check out my none starting car. He was easy to talk to and explained what he was doing. He told me my engine was done, but told me he'd keep trying other things just in case. Nothing worked, but I appreciated the extra effort. He explained what was wrong with it and what the noises my car was making meant. Alexey also gave me some insight on things I could do with the car since it... is now a very big paperweight.I've already told my friends about them, the fair price range and their ability to work on things (when possible) wherever your car is. 10/10 would recommend.read more

Booked a pre purchase inspection ... Got the report they said everrhing was good..2 days later i get the check engine light... can't believe they didn't report the P0456 - Evaporative Emissiom System - Small leak ..which I found using my bluetooth obd tool, not sure how they didn't check for codes during the inspection. Not a happy customer.Edit :They gave me a call and have offered to... diagnose the issue if the check engine light came back. Definitely great customer service.read more

From the very start of the process instaMek were great. They were able to send quotes through almost instantly and were great at communicating. The service we received from our mechanic was exceptional! We would definitely use instaMek again and would definitely recommend them to our family and friends. We had one particular issue we wanted assessed and our instaMek diagnosed that and then spent... the rest of the hour checking everything else in the engine was working how it should. Definitely felt like we got our money worth and the service was great!read more

The service and convenience are HEAVEN!!!My wife dripped off our kids at the arena for a hickey game. As she was parking, there were funny jerks. Thankfully she was able to park. But the car was not starting. She took the kids to the hockey game. While watching the game, she called instamek and left he keys at the information desk for the mechanic. 4 hours later after the warm up, the game,... and dressing the kids, my wife and the kdis walked to the parking to the now fully functioning vehicle. Here is a list of what they did (skme of the work was elevtive as i had asked for it)1) diagnostics2) new sparks plus3) new engine starter4) changed engine oil5) 4 break pads and rotars6) my passenger head lamp (broken from before)7) new battery8) new beltMy wife didnt even meet the mechanic. She disnt even leave the arena. Everything was explained and oid for via the phone call. My next plan is to have my yearly tune ups done while I’m at costco, the gym, or work!!!Thanns guysread more

My brakes gave out on me. These guys came and replaced my breaks/pads and checked my engine the same day for an extremely reasonable price. I am thoroughly impressed with their service, professionalism and would (and have) recommend them to anyone.

I own a Porsche and got the dreaded blinking check engine symbol. I parked my car and begun the search for the right mechanic. Although I have been using the same mech for 2 years since I moved to Calgary, I was tired of driving all the way to the SE from the NW and waiting for hours at his shop since he basically did everything himself.I heard of Instamek through google. After self diagnosing... the issue myself by using my own code scanner, I asked them for a quote. That was my first shock. It was hundreds of dollars less than what mechanic would charge. They adviced me to repair the simple cheap issues first and hope the problem goes away. My Instamek was punctual, well dressed and knowledgeable. 3 cheap fixes later, my Porsche is back!! I will always use Instamek and always request for the same mechanic. I am highly impressed.read more
