Our certified mechanics come to you · 12-month, 12,000-mile warranty
P0915 is a diagnostic trouble code (DTC) for "Gear Shift Position Circuit Range/Performance". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $69.99. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
A P0915 occurs when the vehicle's Powertrain Control Module (PCM) has detected an insufficient range in the transmission gearshift position circuit.
The transmission gearshift system is responsible for determining the engine's power output. In the case of a P0915, the PCM has detected the a limitation in the gearshift's ability to cover its full range. This can result in a series of limitations for the vehicle's transmission system and drivability. A P0915 will occur when there is a reported deviation in the sensed position between two sensors linked up to the PCM.
A P0915 trouble code is most often the cause of bad wiring. Corroded, damaged, disconnected and broken wiring and/or circuitry may be to blame for the malfunction. In rare cases, the vehicle's PCM may be faulty. This instance may also result in a P0915.
A P0915 trouble code will result in harsh shifting, reduced fuel efficiency and, in worst cases, a failure of the vehicle to shift gears.
A P0915 code can be identified with an OBD-II code scanner. All wiring and circuitry related to the sensors and transmission systems should be thoroughly inspected for signs of damage, corrosion or disconnection.
Transmission components may be mistakenly replaced when the sensors themselves are at fault.
Depending on the extent of the sensor deviation (and whether the issue lies with the transmission or the sensor itself), problems can range from harsh shifting to an inability to change gears at all. At its worse, the P0915 code will render the vehicle inoperable. The P0915 code should be tended to as soon as possible.
Check the main and sub-sensors linked up to the PCM and inspect them for proper functionality.
Any components that have been identified as damaged or faulty should be handled accordingly.
Any wiring that has been identified as broken or corroded should be repaired or replaced as the situation demands.
In rare cases, the PCM itself may be at fault. If any repairs are necessary for the PCM, a memory saving device should be attached in order to spare the process the lengthy process of reprogramming.
The specifics of a P0915 trouble code instance will vary depending on the make and manufacturer of the vehicle in question.
