Drive Motor Position Sensor Circuit High Voltage
The P0C62 code indicates that the Powertrain Control Module (PCM) has detected a voltage signal from the drive motor position sensor that is higher than the expected range. This sensor is critical for monitoring the rotor position of the electric drive motor, enabling precise control of motor timing and torque. A high voltage condition can result from a faulty sensor, wiring issues, or a malfunctioning PCM. This code is common in hybrid and electric vehicles and can lead to reduced performance or loss of propulsion.
01. Most Common Causes
- Faulty drive motor position sensor
- Short to voltage in sensor circuit
- Damaged wiring or connector
- Failed PCM
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced motor power or performance
- Vehicle may enter limp mode
- Possible stalling or no-start condition
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to retrieve all codes and freeze frame data.
Step 2: Visually inspect the sensor and wiring for damage, corrosion, or loose connections.
Step 3: Test the sensor signal voltage with a multimeter; compare to manufacturer specifications.
Step 4: Check for shorts to voltage or ground in the circuit.
Step 5: If sensor and wiring are okay, test the PCM for proper operation.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. The vehicle may experience reduced power or sudden loss of propulsion, which can be dangerous, especially at high speeds.
How much does it cost to fix?▼
Repair costs typically range from $150 to $400, depending on the cause. Sensor replacement is usually $150-$250, while PCM replacement can exceed $1000.
