Gear Shift Position Circuit Range/Performance
The P0915 code indicates that the Powertrain Control Module (PCM) has detected an issue with the gear shift position sensor circuit, specifically that the signal from the sensor is out of the expected range or not performing correctly. This sensor tells the PCM which gear the driver has selected (Park, Reverse, Neutral, Drive, etc.). A faulty sensor, wiring issues, or a misadjusted shift linkage can cause this code.
1. Symptoms You Will Notice
- Check Engine Light illuminated
- Transmission stuck in one gear or fails to shift
- Incorrect gear indication on dashboard
- Engine starts in gear or won't start in Park/Neutral
2. Most Common Causes
- Faulty gear shift position sensor
- Damaged or corroded wiring/connectors in the sensor circuit
- Misadjusted or damaged shift linkage
- Internal transmission mechanical issue
3. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm P0915 and check for other codes.
Step 2: Visually inspect the gear shift position sensor and wiring for damage or corrosion.
Step 3: Test the sensor's voltage and resistance per manufacturer specifications.
Step 4: Check shift linkage adjustment and operation.
Step 5: If all else is fine, replace the gear shift position sensor.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
No, it is not safe. The transmission may not shift correctly or could get stuck in gear, leading to loss of vehicle control or transmission damage.
How much does it cost to fix?▼
Repair costs typically range from $150 to $400, including parts and labor, depending on the vehicle and whether the sensor or wiring needs replacement.
