The P2166 fault code in automobiles refers to a problem with the Electronic Throttle Control (ETC) system. The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light, along with no response from the throttle pedal. The cause of this issue could be a faulty ETC, an open or shorted ETC harness, a poor electrical connection in the ETC sensor circuit, or a faulty Powertrain Control Module (PCM).

The importance of repairing this issue lies in the fact that it affects the drivability of the vehicle.

The repair difficulty is moderate, with a repair time of 1.0 hour. To fix the issue, one must visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

If you’re experiencing an illuminated engine light and unresponsive throttle pedal, read on to learn about the symptoms of the p2166 automobile fault code.

  • The automobile fault code P2166 has two main symptoms.
  • The first symptom is that the engine light turns on.
  • The second symptom is that there is no response from the throttle pedal.
  • These are the only two symptoms associated with this particular fault code.

The automobile fault code p2166 can be caused by a faulty ETC, open or shorted ETC harness, poor electrical connection in ETC sensor circuit, or a faulty PCM.

  • The automobile fault code P2166 can be caused by a faulty Electronic Throttle Control (ETC).
  • It can also be caused by an open or shorted Electronic Throttle Control (ETC) harness.
  • Another cause of this fault code is a poor electrical connection in the Electronic Throttle Control (ETC) Sensor circuit.
  • Lastly, a faulty Powertrain Control Module (PCM) can also cause the P2166 fault code.

To fix the p2166 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2166, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code P2166 indicates a problem with the throttle position sensor.

The estimated repair time for this issue is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop. It is important to address this issue promptly to avoid further damage to the vehicle and ensure safe driving.

The P2166 code is related to the electronic throttle of a vehicle. It occurs when the throttle plate fails to reach the upper mechanical stop position within a calibrated amount of time at ignition ON. This code indicates a problem with the ThrottlePedal Position Sensor ‘D’ Maximum Stop Performance.

The Powertrain Control Module (PCM) monitors the electronic throttle for this issue. If the P2166 code sets, it means that the throttle plate is not functioning properly. This issue can cause problems with the vehicle’s acceleration and overall performance.

It is important to have this issue diagnosed and repaired by a qualified mechanic to ensure the safety and reliability of the vehicle.

What are the possible causes of the automobile fault code P2166?

If you’re experiencing an illuminated Engine Light or Service Engine Soon Warning Light, along with no throttle pedal response, the possible cause could be a faulty Electronic Throttle Control (ETC), an open or shorted ETC harness, a poor electrical connection in the ETC Sensor circuit, or a faulty Powertrain Control Module (PCM). To fix the issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or broken, bent, pushed out, or corroded connector’s pins.

How can I fix the issue related to the Electronic Throttle Control (ETC) Sensor circuit?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light, along with no throttle pedal response, it could be due to a faulty Electronic Throttle Control (ETC) or a poor electrical connection in the ETC Sensor circuit. It’s also possible that the ETC harness is open or shorted, or that the Powertrain Control Module (PCM) is faulty. To fix the issue, visually inspect the wiring harness and connectors for any damage or corrosion, and check for broken or bent pins.

What steps should I take to visually inspect the wiring harness and connectors related to the P2166 fault code?

To visually inspect the wiring harness and connectors related to the P2166 fault code, first check for the possible causes listed above. Then, inspect the related wiring harness and connectors for any damaged components. Look for broken, bent, pushed out, or corroded connector’s pins. This will help identify if the Electronic Throttle Control (ETC) harness is open or shorted, or if the ETC Sensor circuit has a poor electrical connection.
