Why would a PCM need to be reprogrammed?
PCM Reprogramming is also necessary to change the engine idle speed, spark timing, fuel mixture or other emission control functions. Reprogramming is often used to modify the operation of emission functions so they have less of an effect on drivability.Click to see full answer.

Furthermore, why would a PCM be reprogrammed?The PCM (powertrain control module) is your car’s on-board computer. The PCM can be reprogrammed to improve the car’s performance or to fix a bug that negatively affects one or more of the car’s characteristics (the car maker creates updates to the PCM software periodically), which is usually done at a dealership.Secondly, what are the symptoms of a bad PCM? Engine stalling or misfiring A faulty computer may cause the vehicle to intermittently have issues such as stalling or misfires. The symptoms may come and go, and may not appear to have any sort of pattern to their frequency or severity. Thereof, how much does it cost to reprogram powertrain control module? Without this system working on top form, you can end up with a number of car problems. The cost of replacing your powertrain control module will be between $450 and $1,630. For labor, you can expect to pay between $45 and $125. Parts should cost you $400-$1,500.How long does it take to reprogram powertrain control module?The reprogramming procedure usually takes 30-40 minutes. 9. When the software has finished loading, it will note that programming is complete. The data is then transferred to the PCM’s memory chip.
