How to Fix P1235 Nissan
- Begin by conducting a thorough inspection of the throttle position sensor, wiring, and connectors. Check for any visible damage, corrosion, or loose connections.
- Use a multimeter to test the voltage output of the throttle position sensor. Compare the readings to the manufacturer's specifications to determine if the TPS is functioning within the acceptable range.
- If the TPS is faulty, replace it with a new sensor. Ensure proper installation and calibration according to the manufacturer's guidelines.
- Clear the diagnostic trouble codes from the ECM memory using a scan tool. Test drive the vehicle to verify that the issue has been resolved and the Check Engine Light is no longer illuminated.
