How much does it cost to change the computer in your car?
Labor will run an hour or two because of the reprogram that needs to happen once the new computer is installed, but the replacement itself is pretty straightforward. All-in-all, the total cost of replacement should be an average of around $1,000, but can be as high as $2,000 for more premium vehicles.
Does dealership charge to reprogram ECU?
For example, you’re easily looking at a $1,000+ job (including parts, labor, taxes, and fees) if you have an ECM repaired at a dealer. If the engine control module just needs to be tested, analyzed, and reprogrammed, it should cost you between $150 and $300.
How much does it cost to have a PCM replaced?
The PCM controls more than 100 factors in your car, and for that reason, is very important – and expensive. A typical pcm replacement cost comes to between $500 and $1,500 on average.
How long does a car computer last?
An ECU is meant to last the lifespan of the vehicle, or at least 100,000 with proper maintenance. The electric control unit works with the currents in the engine to balance fuel and air intake for maximum performance of the engine.
Can I replace an ECM myself?
The answer to the question “Is it hard to replace an ECM?” is NO! The parts themselves aren’t inexpensive (as long as you’re buying them from us!), plus high quality aftermarket and OEM ECMs can be easily installed yourself.
Does a new ECM have to be programmed?
Will A New ECM Need To Be Programmed? Your engine takes a beating over time. While it’s built to last, it needs to be reprogrammed to ensure that everything is functioning optimally. Even if you’re installing a new ECM in your old vehicle, it doesn’t have to be reprogrammed to match its specifications.
How long should battery be disconnected to reset ECU?
Disconnecting the battery for a short time may not do the trick because the car’s computer, or ECU, still has some current in it. Waiting for over 15 minutes after disconnecting the engine will help ensure the equipment is reset.
How do I know if I need to replace my PCM?

How long does it take to replace a PCM?
How long does it take to replace a PCM? 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.
How do you know if the computer is bad in your car?
Usually a bad or failing ECU will produce a few key symptoms that can alert the driver of a potential issue.
- Check Engine Light comes on. An illuminated Check Engine Light is one possible symptom of a problem with the ECU.
- Engine stalling or misfiring.
- Engine performance issues.
- Car not starting.
Can a PCM fix itself?
PCMs are not rebuilt in the same way that alternators and water pumps because there are no mechanical parts that wear out. Remanufacturing in this case usually means testing the computer, isolating and repairing any faults that may be found, then retesting the computer to make sure everything works correctly.
How can you tell if you have a bad ECM?
When the ECM is faulty or failing, it will throw off the timing of fuel settings of the engine. You may notice unexplained drops in fuel efficiency, or you may feel your vehicle struggling to shift. Any sudden change in your vehicle’s performance is reason enough to seek out the source of the problem.
