My car doesn't go pass 20 mph and the warning light says low engine power. How much would this cost to be fixed.
My car has 175000 miles.
My car has an automatic transmission.
Many different types of faulty vehicle components and/or sensors can cause reduced power. Inasmuch as the cost to repair will depend on exactly what must be repaired, a diagnostic to pinpoint the faulty parts must be performed first. That diagnostic costs around $80 to $90. To obtain the diagnostic, that will pinpoint the issue causing the reduced power, please refer to YourMechanic’s reduced engine power diagnostic service request page. If you request that diagnostic, the responding certified mechanic will get the issue pinpointed and then give you an exact repair cost, right at your location. In your circumstance, the vehicle’s powertrain control module (PCM) may have stored one or more diagnostic trouble codes that will identify the "general area" in which the fault lies in the engine management controls. If not, a real time scanner is used to look at actual engine operating data and that will usually reveal enough clues to pinpoint the fault. Although the throttle control system is a common trouble area with reduced power, there are quite a few other components and systems that could come into play and, of course, there is always the possibility of multiple, or "coincident", faults. Here are some of the possibilities that YourMechanic dispatched technicians would consider:
Defective throttle position (TP) sensor
Defective oxygen sensor
Defective accelerator pedal position (APP) sensor
Loose or damaged wiring
Defective throttle body
Defective powertrain control module (PCM) (not typical; ONLY if a long, long list of other possibilities is ruled out)
Any fault/error that will affect drivability function
Any fault/error that will affect vehicle performance
A fault/error in the emissions system
A fault/error in the throttle control system
A fault/error in the transmission control system
If you request the recommended diagnostic the mechanic will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
