How do you know if PCM is bad?
What Are the Symptoms of a Faulty PCM?
- Your “check engine” light is on.
- Other warning lights may be on, including traction control and ABS.
- You lose fuel economy for no apparent reason.
- Your car stutters when starting, requires multiple attempts, or won’t start at all.

What causes PCM 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 much does it cost to replace a PCM?
The PCM is a computer, and computers aren’t cheap to replace. That’s why the average PCM replacement cost is anywhere between $800 and $1,500, depending on the car model and labor costs. Even worse, this is almost all in the cost of the PCM itself. Labor typically only runs between $75 and $100.
How much does it cost to have a PCM programmed?
Prices could range from $80 to $150, depending on the service location you choose. The process takes around about half an hour, but keep in mind that most auto-electricians charge you for at least one hour of work. PCM reprogramming is also one of the few times we’ll recommend a dealership over an independent mechanic.
