Throttle/Pedal Position Sensor Maximum Stop Performance
Code P2167 indicates that the Engine Control Module (ECM) has detected that the throttle or pedal position sensor signal is stuck at the maximum stop position (wide open throttle or fully depressed pedal) for an extended period. This typically occurs due to a faulty sensor, wiring issues, or a stuck throttle plate. The ECM uses redundant sensor signals to verify throttle position; when one signal indicates maximum stop while others disagree, this code sets.
01. Most Common Causes
- Faulty throttle position sensor (TPS) or accelerator pedal position sensor (APP)
- Short or open in sensor wiring or connector
- Stuck throttle plate or binding linkage
- ECM software or hardware failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine power or limp mode
- Poor acceleration or hesitation
- Engine may not respond to pedal input
03. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm code P2167 and check for related codes.
Step 2: Visually inspect the throttle body and pedal assembly for binding, damage, or debris.
Step 3: Test the TPS/APP sensor voltage signals with a multimeter; compare to manufacturer specs.
Step 4: Check wiring and connectors for corrosion, shorts, or opens; repair as needed.
Step 5: If sensor or wiring is okay, replace the throttle body or pedal assembly as per manufacturer procedure.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive with this code as the vehicle may enter limp mode, reducing power and potentially causing unsafe driving conditions. Have it diagnosed and repaired promptly.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnostic and minor repairs like cleaning or wiring fixes. Sensor replacement can cost $100-$300, and throttle body replacement $200-$600, including labor.
