What does p2173 mean in throttle actuator control system?
What does p2173 mean in throttle actuator control system?
This and related codes ( P2172, P2173, P2174, and P2175) all indicate detected air flow problems. Code P2173 is set by the PCM when high air flow is detected in the throttle actuator control system. This code can be related to a Throttle Actuator Control System malfunction, but it is possible that another issue is setting this code.
Why is my throttle position sensor not working?
The reason this happens is that the ECM doesn’t get correct information from the TPS as to how much to throttle the car. Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS.
What are the symptoms of a p2173 trouble code?
Symptoms of a P2173 trouble code may include: Malfunction Indicator Lamp (MIL) or ABS warning lamp illumination Either no or low throttle response Automatic transmission will not shift Additional codes are possibly set Potential causes of the P2173 throttle engine code may include:
What causes idle surges on a car ECM?
Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges.
What causes a p2173 throttle engine code?
Potential causes of the P2173 throttle engine code may include: Engine Overheating Vacuum Leaks (likely on Dodge/Chrysler/Jeep brand vehicles) Manifold Absolute Pressure Malfunction Abnormal System Voltages
What happens when the throttle position sensor fails?
The throttle position sensor can fail in several ways, all of which result in poor fuel economy at best, and performance limitations that may create safety hazard for you and other motorists at worst. This sensor can fail gradually, or all at once. In most cases, the Check Engine Light is illuminated if a TPS failure is detected.
Is there a way to reset the throttle body?
This method is almost foolproof as long as all ECU control parameters are within their normal ranges. Resetting The Throttle Body Calibration (this step is conditional) A Rough Idle or a SES can sometimes be caused by a change in the throttle body position sensor calibration.
What causes a rough idle or a ses?
A Rough Idle or a SES can sometimes be caused by a change in the throttle body position sensor calibration. To correct any accidental changes in throttle body calibration, use these procedures to recalibrate. Note: These procedures are a little tricky to do. You must get the timing just right Use a stop watch to help the precision of your timing.
