This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble with a sensor that checks the temperature when it starts up.
The Powertrain Control Module (PCM), Engine Control Module (ECM), or Transmission Control Module (TCM) has detected an issue with the internal temperature sensor's range or performance.
The P16E3 code indicates that the PCM/ECM/TCM has detected a problem with the internal switch-on temperature sensor, which may be reading outside the expected range or not performing as anticipated. This sensor is crucial for monitoring the temperature of the module to ensure optimal performance and prevent overheating.
• Check Engine Light is on
• Poor engine performance
• Transmission issues
• Faulty temperature sensor
• Wiring issues or poor connections
• Faulty PCM/ECM/TCM
PCM: Powertrain Control Module
ECM: Engine Control Module
TCM: Transmission Control Module
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections to the sensor.
• Test the temperature sensor for proper operation.
• Replace the faulty temperature sensor.
• Repair or replace damaged wiring or connectors.
• Replace the PCM/ECM/TCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Cruze
• GMC Terrain
• Buick Encore
• Regular maintenance checks
• Ensure proper electrical connections
• Avoid overheating the vehicle
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional.
• Avoid driving the vehicle aggressively until repaired.
Check with your vehicle manufacturer for warranty coverage on the PCM/ECM/TCM.
This code is relatively uncommon and typically associated with specific models or manufacturing defects.
Moderate – It should be addressed soon to prevent potential damage to the vehicle.
Driving with a faulty temperature sensor can lead to engine or transmission damage, which may not be covered by warranty if neglected.
• Engine at operating temperature
• Vehicle stationary
The temperature sensor is located within the PCM/ECM/TCM housing.
Q: Can I drive with a P16E3 code?
A: It's not recommended to drive for long periods with this code, as it may cause further damage.
Q: How do I reset the P16E3 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue persists, further diagnostics are needed.
