P2167 code definition
Throttle/Pedal Position Sensor E Maximum Stop Performance
What the P2167 code means
The P2167 code is a general OBD-II diagnostic trouble code (DTC) that indicates a fault with the throttle / pedal position sensor E maximum stop performance. This code may be seen with other throttle body and pedal position sensor codes.
The electronic throttle body uses the signals from the throttle position sensor and the pedal position sensor to determine how far to open the throttle plate allowing air into the engine. The electronic control unit (ECU) detects the maximum stop performance fault with sensor E and triggers the Check Engine Light. The Check Engine Light will be visible on the dashboard and a failsafe mode will be set. This failsafe mode will remain until the code is repaired or normal operation is detected.
What causes the P2167 code?
- Electronic throttle body failure
- Open or short in the sensor wiring harness
- Poor electrical connection
- Throttle position sensor failure
- Pedal position sensor failure
What are the symptoms of the P2167 code?
- Check Engine Light visible on the dashboard
- Engine Misfires
- Car will not start
- Engine stalling
- No or poor acceleration
How does a mechanic diagnose the P2167 code?
Uses a scan tool to check for any codes stored in the ECU. There may be pending and history codes found.
Takes note of all codes present, as well as the freeze frame data for the conditions under which the code was triggered.
Clears all codes for a fresh start.
Takes the vehicle on a road test if it is safe to be driven. The road test will be under similar conditions to the freeze frame data, if possible.
Performs a visual inspection looking for any obvious signs of damage or part failure. The technician will also look for worn or damaged wiring.
Uses a multimeter to check for the proper voltage present at the throttle position sensor as well as the pedal position sensor.
If the proper voltage is found, then the air intake will be removed and the technician will inspect the electronic throttle body for any damage and the ability to function.
Common mistakes when diagnosing the P2167 code
Mistakes are commonly made when there is a failure to follow diagnostic steps. Step-by-step diagnosis is critical to inspect the entire system and not miss simple obvious causes that can be overlooked. It is easy to replace the electronic throttle body as a whole only to find a wiring issue was the only cause.
How serious is the P2167 code?
P2167 can exhibit some rather serious symptoms such as the vehicle not starting, or no acceleration. In vehicles with driveability problems, they should not be driven until the car is repaired. The P2167 code may make the vehicle unsafe to drive.
What repairs can fix the P2167 code?
- Replacing the electronic throttle body
- Repairing or replacing the wiring harness
- Replacing the throttle position sensor
- Replacing the pedal position sensor
- Resolving poor electrical connections
Additional comments for consideration regarding the P2167 code
An advanced scan tool is a critical tool for diagnosing the P2167 code. This type of scan tool allows the technician to view the live data stream in the ECU. The datastream provides information that would otherwise not be obtainable, such as calculated engine load and throttle open percentage.
