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.
What can cause a PCM module to fail?
Water is the primary element to avoid as exposure to it can render the PCM irreparable. Other environmental factors that could lead to PCM failure include thermal stress due to excessive heat and excessive vibration that causes sensitive parts to fail.
How does the PCM work in a car?
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. So before we talk about how to test a PCM, here are some common symptoms of a PCM failure.
What happens when a powertrain control module fails?
As the primary computer control for your vehicle, your powertrain control module (PCM) plays a vital role in ensuring that your engine and transmission work in tandem. When your PCM fails, it typically exhibits one or more different behaviors.

When to replace your PCM ( and when not to )?
The onboard computer is the brains of the engine control system, so when the brain isn’t functioning correctly neither is the engine or anything else that the microprocessor controls – which may include the charging system, transmission, various emission controls and communications with other onboard control modules.
What should my PCM read when the engine is off?
Reconnect any loose wires if necessary. If your PCM has experienced corrosion, you’ll have to skip to step 5 to see if it’s failed. While you’re under the hood, use your multimeter to ensure that your battery has a full charge. It should read at least 12.6 volts with the engine off, or 13.7 volts with the engine running.
What is the error code for a PCM?
We’ve written about several PCM-related error codes in the past, including the P0603 code, the U0100 code, the P0113 code, and the P0606 code. Obviously, this isn’t an exhaustive list, but it represents the most commonly-displayed error codes.
