P0225 - OBD Trouble Code

<<See All OBD Codes

The P0225 fault code can be defined as throttle/pedal position sensor/switch C circuit malfunction. It is a generic OBD-II code which would indicate that the throttle/pedal position sensor/switch C circuit has an internal failure. The sensor has gone out of range, which would cause the throttle to become unresponsive and the engine would go into the failure mode.

Are you willing to learn more about the P0225 fault code? Then you have arrived at the right place. We are always here to help you out. This error code is for one of the multiple sensors for the throttle body control. There are some vehicles which use this sensor to compare the voltage out with the redundant sensors to prevent the issues which are related to the throttle control.

What causes this problem with the Throttle/Pedal Position Sensor/Switch C Circuit?

• Damaged, short circuited, or corroded wiring and connectors
• Defects in the TPS or pedal sensors
• The TPS sensors might be Mal-adjusted
• There can be a mechanical wear in the TPS sensor and/or throttle body
• Carbon deposits in the throttle body that impede the movement of the throttle plate
• While PCM failures do happen, it is a rare event and the fault must be sought elsewhere before any controller is replaced

1. Engine Wiring Connector - OBD Code P0225 can appear because of faulty Engine Wiring Connector. Visit us to solve your issue.
2. TPS or pedal sensors - There can be some issues with the TPS or pedal sensors due to which you may see P0225 code appearing over and over again. Visit us to buy best quality TPS or pedal sensors online.
3. Powertrain Control Module - Are you facing some faults in your Powertrain Control Module? Don’t worry and get them replaced or else P0225 code can turn up.
4. Transmission Sensor - Common cause behind this P0225 error code can be some fault in Transmission Sensor. So, it will be a good decision to replace them now.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0225 here:

Common Symptoms

• The sensor might get ignored during braking
• The throttle might be set to a fixed position during failure on some vehicles
• Issue of uneven idle or jerking while applying brake
• There can be very poor throttle response during acceleration
• The cruise control might be disabled
• The speed of the vehicle might be limited to approximately 32 Mph
• The check engine light and ETC can start illuminating

Want to correct the Trouble Code P0225? Read these points mentioned below:

• Make sure that you repair the battery and charging system for low voltage conditions
• You can always repair or replace a defective connector or wiring to the sensor if it is corroded or has connector damage
• A defective throttle body control assembly should be replaced

Here are some steps which you should follow in order to diagnose this fault code:

• Scan the codes and document the freeze frame data
• The codes should be cleared to verify whether the concern comes back
• You can always do a visual check of the wiring and connections to the throttle body sensor
• Disconnect the connection to the sensor and checks for corrosion, or problems with pin engagement
• Tests for proper battery voltage to the sensor
• The battery should be checked and charging system for proper operation
• Test the sensor resistance and compare it to specifications

Common Mistakes When Diagnosing The P0225 Code

• Carefully inspect the connections to the sensor to make sure they are making good contact to the throttle control assembly
• Make sure that the battery and charging system are working properly
• Inspect the throttle plates for blockage or contamination with oil, dirt or debris
