Gear Shift Position Circuit High
The P0917 code indicates that the powertrain control module (PCM) has detected a high voltage condition in the gear shift position circuit. This circuit monitors the position of the gear shift lever (PRNDL) and sends a signal to the PCM. A high voltage reading typically means there is a short to power, a faulty sensor, or a wiring issue. This can prevent the vehicle from starting or shifting properly.
01. Most Common Causes
- Faulty gear shift position sensor
- Short to voltage in the gear shift position circuit wiring
- Corroded or damaged connector at the sensor
- Faulty PCM (rare)
02. Symptoms You Will Notice
- Engine may not start or cranks but won't run
- Transmission stuck in one gear or fails to shift
- Check Engine Light illuminated
- Incorrect gear indicator on dashboard
03. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm the code and check for additional codes.
Step 2: Visually inspect the gear shift position sensor and its wiring for damage, corrosion, or loose connections.
Step 3: Test the sensor's voltage and resistance with a multimeter according to manufacturer specifications.
Step 4: If wiring and sensor are okay, test the PCM's input circuit for shorts or opens.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
No, it is not safe. The vehicle may not start or could shift unexpectedly, leading to a loss of control. Have it diagnosed and repaired immediately.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and repair, depending on the cause. Replacing the sensor or repairing wiring may cost more.
