P2167 — Throttle/Pedal Position Sensor “E” Maximum Stop Performance #

Note: The exact wording of this code’s description may differ depending on the vehicle manufacturer (OEM). Below are some known label variations:

• Throttle/Pedal Position Sensor “E” Maximum Stop Performance (Generic / SAE)
• Accelerator Pedal Position Sensor E Maximum Stop Performance (Ford)
• APP Sensor E Max Stop Performance (GM, Chevrolet, Cadillac)
• Throttle Position Sensor E Max Limit Exceeded (Toyota, Lexus)
• Pedal Position Sensor E Out of Range – High (Chrysler, Jeep, RAM)

Summary of DTC P2167 #

DTC P2167 indicates a problem with the Throttle/Pedal Position Sensor “E” circuit, specifically that the sensor is reading higher than the expected maximum value when the throttle or accelerator pedal is at its stop position. The Throttle/Pedal Position Sensor (TPS) and Accelerator Pedal Position Sensor (APP) are devices that monitor the angle or position of the throttle plate or accelerator pedal, converting mechanical movement into electrical signals for the engine control module (ECM). When one of these sensors (specifically “E”—most systems use multiple sensors labeled A, B, C, D, E, etc. for redundancy and safety) reports values outside its designed operating range, the ECM sets this code. This is a safety-critical system, as incorrect readings can affect engine performance and, in some cases, vehicle safety.

Common Symptoms for DTC P2167 #

When P2167 appears, drivers may experience a range of symptoms. These can range from subtle to severe, depending on the vehicle’s fail-safe strategy. Often, drivability is reduced as the ECM limits throttle input to prevent unintended acceleration or engine damage.

• Check Engine Light (MIL) illuminated
• Reduced engine power or “limp home” mode
• Poor throttle response or hesitation
• Unusual idle speed (too high or too low)
• Unresponsive accelerator pedal
• Occasional stalling, especially at idle
• Possible traction control or stability warning lights

Probable Causes of DTC P2167 (Most to Least Common) #

Several issues can cause the P2167 code, but some are more common than others. Typically, causes relate to sensor faults, wiring problems, or issues with the throttle body or pedal assembly.

1. Faulty Throttle/Pedal Position Sensor “E” (internal sensor failure or wear)
2. Wiring issues (damaged, corroded, or loose connectors in the sensor circuit)
3. Throttle body or pedal assembly malfunction (mechanical jamming, wear, or misalignment)
4. ECM/PCM failure (rare, but possible if all else checks out)
5. Incorrect installation or calibration after part replacement

Step-by-Step Diagnostic Process for P2167 #

Accurate diagnosis of P2167 requires a logical, step-by-step approach. Rushing can lead to unnecessary part replacements and frustration. Here’s how a qualified technician would tackle this code:

• Verify the code and record freeze frame data using a professional scan tool.
• Visually inspect the throttle/pedal assembly and all associated wiring for damage, corrosion, or loose connections.
• Check the wiring harness for pinched, exposed, or corroded wires between the sensor and ECM/PCM.
• Using a multimeter, measure the voltage and ground at the sensor connector. Compare values to OEM specifications.
• Monitor live data from all throttle/pedal position sensors. Look for “E” sensor readings that are stuck, maxed out, or inconsistent with the others.
• If available, perform an actuator test or “sweep” the pedal/throttle from rest to full and back while monitoring the readings for smoothness and full range.
• If wiring and sensors check out, consult OEM diagnostics for ECM/PCM integrity and consider reprogramming or replacement only as a last resort.

Possible Repairs for DTC P2167 #

The best repair addresses the root cause found during diagnosis. Never simply clear the code and hope for the best—modern vehicles may re-enter limp mode quickly if the fault returns.

• Replace the faulty Throttle/Pedal Position Sensor “E” (often requires replacement of the entire throttle body or pedal assembly)
• Repair or replace damaged or corroded wiring/connectors in the sensor circuit
• Clean or service throttle body or pedal assembly if mechanical binding is found
• Calibrate or relearn the sensor position using OEM scan tool (after repair or replacement)
• In rare cases, replace or reprogram the ECM/PCM if proven faulty (after all other causes are eliminated)

Can You Drive with DTC P2167? #

Limited — Not recommended for regular use. This code often triggers limp mode, drastically reducing throttle response and power for safety reasons. While you may be able to drive short distances to a repair facility, extended driving can be unsafe and may result in stalling or loss of throttle control. If your vehicle displays warning lights, reduced power, or poor drivability, have it diagnosed and repaired as soon as possible.

Vehicles Most Commonly Affected by P2167 #

While P2167 is a generic OBD-II code and can appear on any modern vehicle, it’s more frequently reported on models that use “E” channel sensors for throttle or pedal position. Certain OEMs and platforms are more susceptible based on their design and sensor supplier.

• Ford (F-150, Fusion, Escape, Explorer)
• General Motors (Chevrolet Silverado, GMC Sierra, Cadillac CTS)
• Chrysler/Dodge/Jeep/RAM (Ram 1500, Grand Cherokee)
• Toyota/Lexus (Camry, Tacoma, RX350, Highlander)
• Honda/Acura (Accord, CR-V, Pilot, MDX)

Common Mistakes & Best Practices for P2167 #

Misdiagnosis of P2167 is common, often due to overlooking the basics or skipping steps. Avoid these pitfalls and follow best practices to ensure a successful repair.

• Replacing the sensor without checking wiring/connectors first
• Not performing OEM-required relearn/calibration procedures after repair
• Ignoring related codes (such as for other TPS/APP channels)
• Clearing the code without verifying the fix or duplicating the issue
• Assuming ECM/PCM failure before all other diagnostics are complete

Express FAQ — P2167 #

Q: Does replacing the throttle body or pedal assembly always fix P2167?
A: Not always. If the problem is with wiring, connectors, or a required calibration procedure, simply replacing parts will not resolve the code. Always fully diagnose before replacing components.

Q: Can I reset the code myself and keep driving?
A: You can clear the code with a scan tool, but if the underlying issue isn’t fixed, the code will return—often immediately. Continuing to drive with this fault can be risky and may cause further problems.
