- It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.
P2172: Uncovering The Culprits Behind The Fault Code
There are several causes of the automobile fault code p2172, including a faulty TAC module and a sticking throttle plate due to carbon build-up.
- The automobile fault code P2172 can be caused by a faulty Throttle Actuator Control (TAC) module.
- It can also be caused by an open or shorted Throttle Actuator Control (TAC) module harness.
- Another cause can be a poor electrical connection in the Throttle Actuator Control (TAC) module circuit.
- Additionally, the throttle plate sticking due to carbon build-up can also cause this fault code.
- Finally, the Engine Control Module (ECM) can also be a cause of the P2172 fault code.
It’s best not to rely on the car’s display for fault codes. Decoding the fault code is more accurate and reliable if you use a digital OBD scanner.

P2172: Affordable Fix For Your Car’s Fuel System
The fault code P2172 indicates that the fuel system is too rich. The diagnosis of this code involves checking the fuel pressure, fuel injectors, and the air intake system. The estimated repair time for this fault code is 1.0 hour.
The cost of fixing this code depends on the hourly rate of the auto repair shop, which is usually between $75 and $150 per hour. Other factors that may influence the cost include the severity of the problem, the type of vehicle, and the location of the repair shop.
P2172: Your Engine’s Throttle Actuator Control System Is Malfunctioning
The P2172 code is related to the Throttle Actuator Control (TAC) system. The Engine Control Module (ECM) is responsible for controlling the TAC system.
The ECM calculates the appropriate throttle response based on the driver’s intent.
The TAC system uses two circuits for motor control.
Two processors within the ECM monitor the TAC system data and each other’s data.
The P2172 code indicates a sudden high air flow in the TAC system.
FAQ
