This code means that your car's computer has detected a problem with the signals from the sensors that tell it how much you're pressing the gas pedal. It's like the car is confused about how much you want to go faster or slower.
The P2135 code indicates a discrepancy between the voltage signals from the throttle position sensors A and B, which the engine control module (ECM) uses to determine the position of the throttle.
The throttle position sensors A and B are responsible for providing the ECM with information about the position of the throttle. These sensors send voltage signals that should correlate with each other. If the ECM detects a mismatch in these signals, it triggers the P2135 code. This discrepancy can affect the vehicle's throttle response and overall drivability.
• Check Engine Light is on
• Reduced engine power
• Poor acceleration
• Faulty throttle position sensor
• Wiring issues or poor connections
• Faulty ECM
ECM: Engine Control Module, the computer that manages the engine's functions.
Throttle Body: A component that controls the amount of air entering the engine.
• Use an OBD-II scanner to confirm the code.
• Inspect the throttle position sensors and wiring for damage.
• Check the voltage readings from the sensors using a multimeter.
• Replace the faulty throttle position sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Toyota Camry
• Ford F-150
• Chevrolet Silverado
• Regularly inspect and clean throttle body and sensors.
• Ensure proper maintenance of electrical connections.
• Avoid harsh driving conditions that may stress the throttle system.
Sensor Issue
• Avoid driving the vehicle until the issue is resolved.
• Consult a professional mechanic for accurate diagnosis.
Check with your vehicle manufacturer for warranty coverage on sensors and ECM.
The P2135 code has been a common issue in vehicles with electronic throttle control systems, especially as they age.
High – This code can lead to reduced engine performance and should be addressed promptly to avoid safety issues.
Driving with a malfunctioning throttle system can be dangerous. Address this issue immediately to ensure vehicle safety.
• Vehicle at operating temperature
• Engine running at idle
The throttle position sensors are typically located on the throttle body, which is connected to the intake manifold.
Q: Can I drive with a P2135 code?
A: It's not recommended to drive with this code, as it can lead to unpredictable throttle response and reduced engine power.
Q: How do I reset the P2135 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue persists, further diagnosis is needed.
