P0915 OBD-II Trouble Code: Gear Shift Position Circuit Range/Performance

Check Engine Light

P0915 code definition

A P0915 occurs when the vehicle's Powertrain Control Module (PCM) has detected an insufficient range in the transmission gearshift position circuit.

What the P0915 code means

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.

What causes the P0915 code?

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.

What are the symptoms of the P0915 code?

A P0915 trouble code will result in harsh shifting, reduced fuel efficiency and, in worst cases, a failure of the vehicle to shift gears.

How does a mechanic diagnose the P0915 code?

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.

Common mistakes when diagnosing the P0915 code

Transmission components may be mistakenly replaced when the sensors themselves are at fault.

How serious is the P0915 code?

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.

What repairs can fix the P0915 code?

Additional comments for consideration regarding the P0915 code

The specifics of a P0915 trouble code instance will vary depending on the make and manufacturer of the vehicle in question.
