#Chevy cobalt 2006 code p2176 code
Tighten: Tighten the fasteners to 10 Nm (89 lb in). 2006 Chevy Cobalt - 3,400 image 1 of 11 QR Code Link to This Post. If DTC P1516, P2101 and/or P2176 are not set, proceed to Step 28. Both processors monitor each other's data to verify that the indicated throttle position is correct. and/or P2176 set If DTC P1516, P2101 and/or P2176 are set, replace the throttle body. Both processors are located within the ECM. In conclusion, the P2176 code is a diagnostic trouble code that refers to a problem with the throttle body actuator/motor and has failed to learn the correct. If the throttle body is cleaned without performing an 'idle learn reset/reset idle learn' with the Tech 2, the ECM/PCM may continue to compensate for previous carbon build up, causing it to return with a similar concern as well as DTCs P0121, P0506, and/or P0507. This part is in charge of different body functions, such as the keyless entry, mirror features, washers, and wipers. Two processors are also used to monitor the TAC system data. Your vehicle has a body control module (BCM) that receives information from different switches and sensors scattered throughout your vehicle. The TAC system uses the following circuits for Motor control 1 and Motor control 2. The ECM achieves throttle positioning by providing a pulse width modulated voltage to the TAC motor.

The ECM determines the drivers intent and then calculates the appropriate throttle response. The Engine Control Module (ECM) is the control center for the Throttle Actuator Control (TAC) system. This type of relay typically uses a five-wire design. It is a contact type relay that is activated with a signal wire from the ignition switch. The PCM power relay is used to apply battery voltage safely to the appropriate PCM circuits. I have a 2006 Cobalt showing engine power reduced, and reading OBD codes: P2135 P2176 P1516 AND P060E. This code will be stored if power relay sensor circuit voltage is lower than expected. Throttle plate sticking due to carbon build-up The cost to diagnose the P1516 CHEVROLET code is 1. 2007 chevy cobalt 2.2L Ecotch 4 cylnder, Engine code engine poor reduced performance code P2176. If the head cannot be repaired, it will need to be replaced. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. The cylinder head would need to come off, the valves cleaned or replaced, and the valve seats repaired. P2176 is a diagnostic trouble code (DTC) for 'Throttle Actuator Control System - Idle Position Not Learned'. Throttle Actuator Control (TAC) module circuit poor electrical connection This will give a misfire and lean AT IDLE ONLY. Throttle Actuator Control (TAC) module harness is open or shorted The P2176 code is set when the difference between the predicted and the actual throttle position is more than a calibrated amount for more than 1.5 seconds.įaulty Throttle Actuator Control (TAC) module
