When to look for a powertrain control module?
If you find that these symptoms apply to your powertrain control module, then you should look into a powertrain warranty. The first symptom that the powertrain control module has been damaged is that the check engine light comes on. If the check engine light illuminates with codes, sometimes these codes can’t be repaired.
What are the symptoms of a faulty PCM?
To help you out, we’ve put together a handy guide. What Are the Symptoms of a Faulty PCM? Many of your car’s functions are controlled by the powertrain control module (PCM), which works in conjunction with the engine control module (ECM) and transmission control module (TCM) to adjust engine timing, the air to fuel ratio, and other systems.
How to diagnose a bad engine control module?
The best way to diagnose an engine control module fault is to understand its main responsibilities. Once you are aware of these primary functions, it becomes easier to determine what symptoms are bad PCM symptoms.
What causes a powertrain control module to stop firing?
Intermittent misfires are a huge indicator of a malfunctioning ECU. When the ECU does not analyze the information correctly, then it can cause certain cylinders to stop firing. Normally, these misfires occur at random with no set pattern.
How can I tell if my powertrain control module is bad?
Another more obvious sign is when all the dashboard error lights engage and disengage continuously. To determine whether these trouble signs stem from the PCM, next, you can use a code reader to link to the PCM to identify. These devices connect directly into a port known as the Onboard Diagnostic or OBD-II connector port.
What is the powertrain control module in a car?
The powertrain control module, otherwise known as the PCM or computer, is essentially your vehicle’s brain. The PCM in your car or truck is designed to control and regulate all of its functions and parts.
