How to handle the P2135 trouble code?

p2135 trouble code processing method is: 1. Eliminate the connection problems of the throttle body position sensor plug and wiring harness; 2. Replace the throttle position sensor; 3. Replace the new throttle body. The P2135 trouble code refers to the voltage correlation fault between the throttle, accelerator pedal position sensor, and switches A and B. In the electronic throttle control system, the function of the accelerator pedal position sensor is to transmit the position of the accelerator pedal to the throttle control module in the form of an electrical signal, which serves as a reference for the throttle actuator to control the opening of the throttle valve.

Encountering the P2135 trouble code can be quite frustrating, as I've personally experienced similar issues. This code typically indicates a mismatch in the throttle position sensor's signal voltage, possibly due to a dirty sensor or loose connection. I recommend first turning off the engine to check for loose or corroded wiring connectors - if found, clean them gently with a soft cloth and reconnect securely. If the sensor is contaminated with oil, you can spray some throttle body cleaner and wipe it lightly. If the warning light persists after cleaning and restarting, consider replacing the sensor or checking the ECU. This issue can cause weak acceleration, skyrocketing fuel consumption, and significantly impact daily driving experience. If you can't solve it after considerable effort, it's wiser to visit a professional repair shop rather than wasting money on fuel.

As someone who frequently tinkers with cars, I'm quite familiar with P2135. It indicates a mismatch in the voltage signals from the two throttle position sensors. When dealing with this issue, first connect an OBD scanner to read the data and confirm the voltage difference. Check if the sensor is severely carbon-fouled, then disassemble and clean it with professional cleaning agent. Don't overlook the wiring - use a multimeter to test for short circuits or open circuits, and repair or replace corroded wires. If voltage-related faults persist, reset the engine control unit or replace the sensor. Throttle control affects throttle response and emissions, so after repairs, test to ensure smooth acceleration and reduced exhaust issues.

Fault code P2135 indicates a throttle sensor signal error, which is extremely dangerous and may cause the engine to stall or acceleration to become uncontrollable while driving. My approach is to immediately pull over, stop the vehicle, and turn on the hazard warning lights. Do not attempt to repair complex circuits yourself to avoid the risk of electric shock. Contact a professional technician immediately for diagnosis, cleaning, or replacement of components. Sensor failures reduce vehicle stability and pose life-threatening risks, requiring prompt repair. Paying attention to abnormal engine sounds during daily use can help with early prevention.
