P0227 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The P0227 trouble code can be defined as throttle/pedal position sensor/switch C circuit low input. It is a generic OBD-II code which would indicate that the throttle/pedal position sensor/switch C circuit has a low input problem which is causing the sensor input to the ECM to be lower than the expected voltage input as compared to the redundant throttle position A.

Are you willing to learn something more about this fault code? It is always good gain more knowledge, that’s why we are here to help you out. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. This code would indicate that the powertrain control module has detected a throttle pedal position sensor switch C circuit voltage reading that is abnormal.

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

• The engine control module might detect the sensor circuit voltage below the specified range for the sensor.
• Short to ground in the signal cable can cause low voltage to the engine control module
• There can be an open circuit in the signal cable from a break in the wire, or corrosion in connections.

1. Pedal Position Sensor - A faulty Pedal Position Sensor can be troublesome. You can always rely on us as we have best auto parts for our customers.
2. Engine Control Module - If everything is alright with Pedal Position Sensor, then there is surely some defect in Engine Control Module. Get it replaced before the situation gets worse.
3. Engine Wiring Connector - P0227 code can display due to some faults in the Engine Wiring Connector. So, it is very important to replace the Engine Wiring Connector with us at equitable prices.
4. Digital Multimeter - Willing to buy Digital Multimeter online? We are here at your service!

It is vital 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 P0227 here:

Common Symptoms

• Check engine light and electronic throttle control light can start illuminating
• The throttle might shut completely during stops
• The throttle sets to a fixed position during acceleration failure
• Issue of uneven idle or jerking during braking due to the closed throttle position
• Acceleration is limited by very poor throttle response, or no response at all, during acceleration
• Vehicle speed might be limited to 32 mph or less

Looking out for some ways with the help of which you can correct this fault code? Then have a look below:

• Repair or replace the defective connector or wiring to the sensor if it is corroded or has connector damage
• The cuts or shorts in the wiring to the sensor should be repaired
• You can always replace the throttle body control assembly if defective
• The engine control module should always be repaired or replaced if suggested by pinpoint tests

Parts Avatar Canada endeavours to fulfil all the needs of its consumer, that’s why we have a huge collection of top-quality Throttle Return Spring, Automatic Transmission Module, Throttle Body Spacer and Tps sensor and many more at equitable prices. We won’t let you down in any way.

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 P0227 Code

• It is very important to visually check the connections to the sensor to make sure they are making good contact to the throttle control assembly
• Carefully search for any problems with burnt or cut wiring to the sensor, or corrosion in the connections
