Guide To P2166 OBD Error Code Solutions

<<See All OBD Codes

Error code P2166? No worries, all you need is this little guide by Parts Avatar to solve the error code. The OBD-II code P2166 is known as a throttle/pedal position sensor "D" maximum stop performance. It should be noted that the throttle position sensor/switch can be situated on the throttle body of the intake manifold while the pedal position sensor/switch is a segment of the accelerator pedal assembly. The engine control module (ECM) is informed by these sensors about the speed of the driver. It also regulates and guides about how fast it should function to achieve the required speed. When the PCM identifies a defect with this sensor or the circuit of this sensor, the code P2166 is stored. At times, the PCM also limits the speed of the vehicle to 20 miles per hour or less ("limp home mode") to prevent the engine and the driver. It happens due to the control module’ inadequacy to precisely detect the engine performance being requested.

This code P2166 is a general OBD-II trouble code that registers a malfunction with the throttle pedal position sensor circuit. The position of the throttle pedal is noted by the throttle position sensor so that throttle actuator ensures the desired engine acceleration. The powertrain control module (PCM) along with other control modules such as fuel injection control module, transmission control module, and turbo control module receive data from the throttle pedal position sensor. When an error is detected in the throttle pedal position sensor circuit or throttle actuator control motor circuit by one of the control modules,the trouble code P2166 is stored.

What causes this problem with the Throttle/Pedal Position Sensor D Maximum Stop Performance?

• Damaged throttle position sensor
• A malfunctioning throttle position actuator
• A defective throttle actuator control motor
• Defective electrical components in the system (especially in the throttle actuator motor)
• Broken ground wire
• Disconnected control module ground strap
• A fault in the PCM

15. Throttle actuator motor - Still have problems with the throttle position sensor? Experiencing problems like a low acceleration? Rough or slow idle? Stalling? Don’t you worry, Parts Avatar has it all. A faulty throttle actuator motor could end up being the root cause stimulating the error code P2166.
16. Accelerator pedal position assembly - It is notable that whenever a problem with the accelerator pedal position assembly exists, it affects the APP sensor that further leads to a reduction in the vehicle's ability to consistently accelerate or decelerate. Mend or restore your accelerator pedal position assembly as soon as possible in order to avoid further complications caused by the error code P2166.

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

Use an OBD-II trouble code scanner to diagnose the error code P2166. The scanner should be used to view the freeze frame data by the technician to help examine the P2166 code. It should also be used to check for additional trouble codes. Also, it is important to attend the codes in the order in which they are stored.

After this the codes should be cleared and the vehicle should be retested by the technician to see if the code returns. If the code does not reappear, then it was most probably triggered erroneously or reflects an intermittent error.

If the P2166 code reappear, then the technician should perform a visual inspection of the electrical components in the throttle actuator and throttle position systems along with the controller area network (CAN). All the blown fuses, corroded connectors or wires that are short circuited, should be replaced or repaired. The ground wires and straps should be inspected too. The voltage and ground signals should then be probed for the throttle position sensor and the throttle actuator control motor to ensure they fall within the manufacturer’s specifications. If the problem reappears, then a thorough inspection of the control modules should be performed.

Lastly, now that the replacement of the components is done, the technician should halt the inspection. The codes should be reset and the vehicle should be test driven to see if the code returns. This will be helpful in determining whether the code is resolved or not.

Common Mistakes When Diagnosing the P2166 Code

Here we have listed a few common mistakes that should be avoided while diagnosing the error code:

Mostly, the mistake committed while diagnosing the code P2166 is an unsuccessful attempt to parallel the OBD-II trouble code diagnosis protocol. It is advised to follow the protocol accurately in order to make sure that all the inspections and repairs are correct effective. Also, the code P2166 is often followed by a number of other trouble codes. And it is common for the additional codes being independently when they reflect a reaction to the P2166 code. One should be careful, as it is highly essential to address the codes in the order in which they appear to make sure that the problem is fixed right from the beginning. Most of the times, solving the P2166 code will resolve other present codes too.
