Can you do a diagnostic without a trouble code?
Throughout the years, more emission related systems and components have been incorporated to the list of computer monitored systems. Still, some performance and driveability problems can appear without the computer setting any DTC. So you need a different strategy to do a diagnostic without the help of a trouble code.
When do you have a bad Powertrain Control Module?
If you are getting codes for a faulty oxygen sensor, for example, and you have replaced all the related components but the check engine light remains illuminated, then you may have a bad PCM. The ECU is responsible for many areas of the vehicle that control whether or not the vehicle starts.
How can you tell if your engine control unit is failing?
The complexity of a vehicle’s engine control unit (ECU/PCM) can often make it very difficult to determine when it’s failing. It’s very common for your vehicle to display symptoms that appear to be an ECU issue when, in fact, there is actually an issue elsewhere in your vehicle or vice versa.
What happens when the ECU is not working?
The ECU is related to this because it controls the timing of the spark plugs. If the computer is not working properly then it can impact when the spark plugs fire or stop them from firing altogether. If the vehicle is not getting spark, then it will not run.
