Code P1815 GMC Description
The P1815 GMC code indicates a malfunction in the Automatic Transmission (A/T) Range Sensor circuit. The A/T Range Sensor, also known as the Transmission Range Sensor (TRS) or Neutral Safety Switch, is a crucial component that communicates the gear position of the transmission to the Engine Control Module (ECM). This information is essential for the ECM to determine the appropriate shifting strategy, torque converter lockup, and other transmission functions.
Common Causes of P1815 GMC
- Faulty A/T Range Sensor
- Damaged wiring or connectors in the sensor circuit
- Corrosion or poor connection in the sensor circuit
- ECM software or programming issues
- Mechanical damage to the transmission range sensor
Symptoms of P1815 GMC
- Rough or delayed shifting
- Inability to shift into certain gears
- Transmission slipping
- Vehicle not starting
- Check Engine Light illuminated
How to Fix P1815 GMC
- Diagnose the issue by using a scan tool to retrieve the trouble code and inspecting the A/T Range Sensor and its circuit for any visible damage.
- Test the A/T Range Sensor using a multimeter to check for proper voltage, resistance, and continuity.
- Inspect the wiring and connectors in the sensor circuit for any signs of damage, corrosion, or poor connections. Repair or replace as necessary.
- Clear the trouble code from the ECM memory and test drive the vehicle to ensure the issue has been resolved.
- If the problem persists, consider reprogramming the ECM or replacing the A/T Range Sensor with a new one.
Cost to Fix P1815 GMC
The typical repair costs for addressing a P1815 GMC code can range from $200 to $500, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. Auto repair shops commonly charge between $80 and $150 per hour for labor, but rates may be higher in metropolitan areas or at dealerships.
