Code P1E35 Chevrolet Description
The P1E35 diagnostic trouble code for Chevrolet vehicles indicates a problem with the Auxiliary Transmission Fluid Pump Inverter Temperature Sensor Circuit, specifically low voltage. In hybrid or electric vehicles, such as the Chevrolet Volt, the auxiliary transmission fluid pump is responsible for circulating transmission fluid to help maintain optimal operating temperatures. The inverter temperature sensor monitors the temperature of the transmission fluid pump to ensure it stays within safe operating limits.
Common Causes of P1E35 Chevrolet
- Faulty Temperature Sensor: The most common cause of this code is a malfunctioning inverter temperature sensor that is not providing accurate readings to the vehicle's computer.
- Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connecting the sensor to the computer can also trigger this code.
- Pump Inverter Failure: A malfunctioning auxiliary transmission fluid pump inverter can cause low voltage readings in the sensor circuit.
- Software Glitch: In some cases, a software glitch in the vehicle's computer system can falsely trigger this code.
Symptoms of P1E35 Chevrolet
- Illumination of the Check Engine Light: The most common symptom associated with this code is the activation of the Check Engine Light on the vehicle's dashboard.
- Transmission Overheating: If the transmission fluid pump is not circulating fluid properly, it can lead to overheating of the transmission system.
- Reduced Fuel Efficiency: A malfunctioning auxiliary transmission fluid pump can cause the vehicle to consume more fuel due to increased resistance in the transmission.
- Transmission Slipping: In severe cases, the transmission may start to slip or shift erratically due to improper fluid circulation.
How to Fix P1E35 Chevrolet
- Diagnose the Issue: Begin by using a scan tool to read the trouble codes and perform a thorough inspection of the auxiliary transmission fluid pump inverter temperature sensor and related components.
- Replace the Temperature Sensor: If the sensor is found to be faulty, replace it with a new, OEM-quality sensor.
- Check Wiring: Inspect the wiring harness for any signs of damage, corrosion, or loose connections. Repair or replace any faulty wiring.
- Test Pump Inverter: Check the functionality of the auxiliary transmission fluid pump inverter to ensure it is operating correctly.
- Clear Codes and Test Drive: Once the repairs are completed, clear the trouble codes from the vehicle's computer and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P1E35 Chevrolet
