Experienced mechanics share their insights in answering this question :
Once a trouble code is erased, it cannot be retrieved. The engine controller does not have a "recycle bin" like they have on Windows. If the car still has a problem, the code will come back up after some driving. However, the controller will not turn on the CEL until it has seen the malfunction on two separate "trips." A "trip" is a driving cycle where the car is started cold, driven until it is fully warm and through a certain number of accelerations, and shut down. So you might not see the CEL for a couple of days. As for the "head gasket sealer," I wouldn’t hold out too much hope of that solving a problem. At the very best it might put off the symptoms for a short while. If you need help interpreting codes that come up, or solving a head gasket issue, contact Your Mechanic. They can send a technician to your home or office to read the codes on your car and help you decide what to do.

When you reset your computer`s memory, the warning light will turn off. However, if there`s a problem, the light will come back on as soon as the computer runs the test that caused the light in the first place.
In general, you will need to drive between 50-100 miles after you clear your car`s computer. Hopefully, this will get rid of the check engine light once and for all.
The reasons for a check engine light turning on can range from something minor like a loose gas cap to something more serious like a faulty catalytic converter. It could even be a sign of internal engine failure. Ignoring the problem can turn a potentially quick fix into a costly and time-consuming repair.
There are thousands of possible diagnostic codes possible, some that are specific to a manufacturer or particular vehicle, and many that are generic across all vehicles.
So, with the right diagnostic scan tool, automotive technicians can quickly and easily read the codes and data from your vehicle, even if the check engine light isn`t on.
Erasing error codes deletes the errors from the computer. In doing so, you lose the information that would help solve a problem with the car, so you shouldn`t erase them unless the problem has been corrected. Erasing them to pass a smog test generally won`t work.

I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you
Car won’t move. I can start the car but when I put the shifter in 1st, 2nd, 3rd, ect. The car will not move.
ANSWER : The transaxle is not engaging internally to the axle shafts inside the transaxle or you have one or both axle shafts disengaged from the transaxle. The fact that the speedometer moves when gear is engaged and clutch is released shows the speed sensor in the transaxle is getting turned.
You will need to have the vehicle raised and the axles inspected for broke or stripped shafts. If the axles do not have anything visually wrong with them then hold one wheel and try to turn the other wheel while transaxle is in gear, with engine off, to see if the wheels are locked together. When you spin one wheel the other wheel should turn in the opposite direction. If it does not then the problem is in the transaxle differential gears and the transaxle would need to be removed and disassembled to find the broken internal components.

Check Engine Light is on – codes P0313, P0299, P0304
ANSWER : Hi there. Based on what you’ve described, this could be a combination of faults between 2 or more things; however, I don’t believe the coils and spark plugs are at fault. One of the codes is set during a low fuel misfire (lean condition), one is specifying a misfire on cylinder 4, and one is a turbo related code; all based on a generic code investigation.
The make and model of the vehicle helps, but is not necessary at the moment. When a low fuel pressure misfire is set, there is a lean condition that has been detected by the sensors and one of the codes is telling us in which cylinder this is occurring. A possibility is a restricted fuel injector, loose injector harness, poor pin fit in the wire harness, and an air leak near that cylinder’s port in the intake manifold.
I’m leaning more towards a leak or crack somewhere creating an air leak since we also have a turbo related code stored and an intermittent rough start when cold. I strongly suggest having a qualified technician perform an inspection to determine the root cause. YourMechanic has several available technicians that can assist you with a Check Engine Light inspection and determine exactly what is giving rise to codes P0313, P0299, and P0304.
I filled my car up with gas, drove about a block to get a newspaper, put it in park and it died before i ever got out of the car .
ANSWER : With a car that cranks but won’t start, there are a few things that need to be checked. But before I explain them, there is a common thing that happens with Nissan’s. Every once in awhile they will flood the cylinders with fuel and wash the oil film off the cylinder walls and rings. This will reduce compression enough that the car will not start. Fortunately, there is an easy fix for this problem. It is what is known as clear flooding.
Hold the gas pedal all the way to the floor while cranking the motor. It won’t start immediately and when it does it will not run very well at first. Feather the throttle to keep it running until the motor clears out the excess fuel and the motor begins to run smoothly. If after cranking the motor with the gas pedal held to the floor for at least
I pulled into a parking spot and put my car into park, when I lifted my foot from the brake the car continues forward.
ANSWER : The vehicle transmission did not get back to the park position due to the shift cable came off of the transmission shift linkage. You will need to have a mechanic like one from YourMechanic come to you and check the shift cable connection at the transmission to see if the shift cable bushing broke and let the cable end disengage from the shift linkage. The shift cable may need replaced if the cable end bushing is not available. I recommend a mechanic check the shift cable and replace cable or repair cable end as parts allow.
My Car drives forward not backwards. In N and R rolles forward, but will not roll back. Have to lift front to move the car beck.
ANSWER : Hi there. Make sure the vehicle is on level ground with the engine warmed up when checking transmission fluid. Check the fluid for color, smell, and contamination as these could be telltale signs of what is occurring inside the transmission. It does sound like there is a shift solenoid that is not activating; this could be the 1-2 shift solenoid or the low/reverse solenoid depending on how many are in your particular transmission. These are simply valves that control the flow of hydraulic fluid used by the transmission control computer to determine the gear selection for the transmission. These solenoids can be manually activated in the same way you have described by selecting D1, D2, and so on. Since there was no change in the transmission operation when you selected D1, this could be a solenoid or electrical circuit fault. The solenoid could be mechanically broken/stuck or there could be an open circuit in the solenoid or the electrical circuit itself. Properly testing this system and components should be performed by a qualified technician and I strongly urge you utilize one for this inspection to avoid replacing unnecessary parts.

My heat in my car stopped working two days ago and now my car is overheating. I put antifreeze in my car and it’s still overheating 2006 Pontiac Grand Prix
ANSWER : Hi there – you may have 2 related events here, a coolant leak, and a problem with the heater system. The current issue may be air inside the cooling system, which can cause overheating, and a lack of heater function. The lack of heater function could have 5 causes: the engine is not getting up to correct temperature (center of the gauge) due to a malfunctioning thermostat, the heater control valve is not letting hot coolant into the heater core, there is a restriction in the heater system that is preventing adequate hot coolant flow through the heater core, the heater fan is not working to transfer heat from the heater core to warm air for the passenger compartment, or the air blend doors inside the heater are not working properly to route warm air to the desired vents. I would recommend a heater system inspection](https://www.yourmechanic.com/services/heater-is-not-working-inspection) by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
