Throttle/Pedal Position Sensor "E" Maximum Stop Performance
P2167 indicates the throttle/pedal position sensor E is reading at or beyond its maximum threshold, preventing normal engine throttle control. This sensor measures pedal position to determine driver intent, and when it fails, the engine cannot properly regulate fuel and ignition timing, making the vehicle potentially undriveable and unsafe to operate.
What You Might Notice
- Lack of throttle response or delayed acceleration
- Limited or no acceleration capability
- Engine stall during idle or low-speed driving
- Hesitation or jerking when accelerating
- Cruise control inoperative or disabled
Most Common Causes
- 1
Defective throttle/pedal position sensor E
The sensor itself has failed or is providing an out-of-range signal, causing the ECU to detect maximum voltage or position reading. This is the most common cause of P2167.
- 2
Wiring or connector issues
Corroded, damaged, or loose connections on the sensor wiring harness can cause false maximum readings. Poor grounds or shorted wires may trigger the code.
- 3
Throttle body or pedal assembly failure
Mechanical binding, damage, or wear in the throttle body or accelerator pedal assembly can cause the sensor to stick at maximum position.
- 4
ECU or control module malfunction
The engine control unit itself may be faulty and misinterpreting normal sensor signals as maximum values, though this is less common.
How to Diagnose It
- 1
Check Defective throttle/pedal position sensor E — The sensor itself has failed or is providing an out-of-range signal, causing the ECU to detect maximum voltage or position reading. This is the most common cause of P2167.
- 2
Check Wiring or connector issues — Corroded, damaged, or loose connections on the sensor wiring harness can cause false maximum readings. Poor grounds or shorted wires may trigger the code.
- 3
Check Throttle body or pedal assembly failure — Mechanical binding, damage, or wear in the throttle body or accelerator pedal assembly can cause the sensor to stick at maximum position.
- 4
Check ECU or control module malfunction — The engine control unit itself may be faulty and misinterpreting normal sensor signals as maximum values, though this is less common.
How to Fix It
- 1
Replace throttle/pedal position sensor E
Remove the defective sensor and install a new OEM or equivalent replacement. Ensure proper connector seating and wiring orientation. Clear the code after replacement and verify throttle response returns to normal.
- 2
Inspect and repair wiring and connectors
Examine the sensor harness for corrosion, breaks, or loose pins. Clean corroded connectors with electrical contact cleaner or replace damaged wiring. Verify proper ground connections and crimp any loose terminals.
- 3
Clean or service throttle body and pedal assembly
Inspect the throttle body and accelerator pedal for mechanical binding or carbon buildup. Clean with appropriate throttle body cleaner and verify smooth operation through full range of motion.

Replace engine control module if needed
If sensor and wiring tests pass, the ECU may be faulty. Programming of a replacement module may be required and should be performed by a qualified technician with proper diagnostic equipment.
