P0225 code definition

Throttle/Pedal Position Sensor/Switch C Circuit Malfunction

What the P0225 code means

P0225 is a generic OBD-II code which indicates that the throttle/pedal position sensor/switch C circuit has an internal failure. The sensor went out of range, causing the throttle to become unresponsive and the engine to go into failure mode.

What causes the P0225 code?

The engine control module (ECM) detects sensor circuit voltage above or below the specified range designed for the sensor over a specified time.

What are the symptoms of the P0225 code?

  • The sensor is ignored during braking
  • The throttle may be set to a fixed position during failure on some vehicles
  • Uneven idle or jerking during braking
  • Very poor throttle response during acceleration
  • The cruise control will be disabled
  • The vehicle speed will be limited to approximately 32 mph
  • The Check Engine Light and ETC light will be illuminated

How does a mechanic diagnose the P0225 code?

  • Scans codes and documents the freeze frame data

  • Clears the codes to verify whether the concern comes back

  • Does a visual check of the wiring and connections to the throttle body sensor

  • Disconnects connection to the sensor and checks for corrosion, or problems with pin engagement

  • Tests for proper battery voltage to the sensor

  • Checks the battery and charging system for proper operation

  • Tests the sensor resistance and compares it to specifications

Common mistakes when diagnosing the P0225 code

Follow these simple guidelines to prevent misdiagnosis:

  • Do a visual check of 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 is working properly

  • Check the throttle plates for blockage or contamination with oil, dirt or debris

How serious is the P0225 code?

  • The vehicle speed will be limited to less than 35 mph
  • The engine may hesitate or lack acceleration
  • The engine idle will be erratic and be set higher than normal

What repairs can fix the P0225 code?

  • Repairing the battery and charging system for low voltage conditions

  • Repairing or replacing a defective connector or wiring to the sensor if it is corroded or has connector damage

  • Replacing a defective throttle body control assembly

Additional comments for consideration regarding the P0225 code

The code P0225 is for one of the multiple sensors for the throttle body control. Some vehicles use the sensor to compare voltage output with the redundant sensors to prevent throttle control issues. This code may have various drive symptoms, depending on the manufacturer's failure mode.

Omar arrived right on time. He was thorough in running through all of the points of the inspection, and when he found the cause of the check engine light, he explained it in detail. Thankfully, it was a minor issue and easy remedy. He noticed a few things that I needed to pay attention to and sent me an estimate for them. He was friendly, polite, and knowledgeable.
