OBD-II Generic Error Code P2795: How to Fix It

Q: Can I drive my car with a P2795 code?

In many cases, your vehicle may still be driveable with P2795 active, but it is not recommended for extended driving. The faulty gear shift direction signal can cause unpredictable transmission behavior, erratic shifting, or the transmission entering a failsafe or limp mode that limits vehicle speed. Have the issue diagnosed and repaired as soon as possible to prevent further transmission wear or damage.

Q: What is the most common cause of P2795?

The most common causes of P2795 are damaged or corroded wiring and connectors in the gear shift direction circuit, a failed or out-of-range gear shift direction sensor, or a poor ground connection causing the circuit voltage to read too high. A faulty TCM or PCM is possible but far less common and should only be considered after all wiring and sensor issues have been ruled out.

Q: Will P2795 clear itself after a repair?

P2795 will not clear itself automatically right away. After making a repair, you need to use an OBD2 scanner to manually clear the code. The vehicle's PCM will then run its self-tests over one or more complete drive cycles. If the underlying fault is truly fixed, the code will not return. If the root cause was not fully resolved, the code will reappear.

Q: How much does it cost to fix a P2795 error code?

Repair costs vary depending on the root cause. A simple wiring repair or connector cleaning may cost $50–$150 in labor at a shop. Replacing the gear shift direction sensor typically costs $100–$300 including parts and labor. If the TCM or PCM is at fault, costs can range from $500 to over $1,500 depending on the vehicle, due to the cost of the module itself and the required reprogramming.

Q: Is P2795 the same as P2793 or P2794?

No, though they are closely related. P2793 refers to a general gear shift direction circuit fault, P2794 refers to a circuit low voltage condition, and P2795 specifically identifies a circuit high voltage condition. All three involve the same gear shift direction circuit but indicate different electrical faults. If multiple codes appear together, they can help narrow down whether the issue is a short to voltage, a short to ground, or an open circuit.

Abstract

The P2795 error code means your vehicle's powertrain control module (PCM) has detected an abnormally high voltage signal in the gear shift direction circuit, which is part of the transmission control system. This circuit tells the transmission which direction the driver intends to shift, and when it reads too high a voltage, the PCM logs this fault and may trigger a warning light. Left unaddressed, this can affect transmission behavior, cause erratic shifting, or prevent smooth gear changes, so it's worth diagnosing promptly.
