How to Fix Error Code P2167
-
Read and Record All Stored Codes
Do not clear codes before recording them. Clearing codes erases valuable freeze frame data that helps diagnose the problem. -
Inspect the Throttle Body and Sensor Wiring
Always ensure the ignition is fully off and the key is removed before handling any wiring or connectors to avoid accidental electrical shorts. -
Test Throttle Position Sensor Voltage
Be very careful when probing live circuits. Do not allow probe tips to slip and short against each other or ground. Keep hands away from moving engine components. -
Check Throttle Body for Carbon Buildup
Never force the throttle plate open manually on electronic throttle control (ETC) systems, as this can damage the throttle actuator motor. Be gentle when cleaning. -
Perform a Throttle Body Relearn Procedure
Skipping the throttle relearn after cleaning or replacing the throttle body can result in rough idle, stalling, or the check engine light returning immediately. -
Replace the Throttle Position Sensor or Throttle Body Assembly
Disconnect the negative battery terminal before replacing any throttle body components to prevent accidental deployment of electronic systems. Allow at least 5 minutes after disconnecting the battery before working on the throttle body. -
Inspect the ECM/PCM Power and Ground Circuits

When to Call a Professional
You should seek help from a professional mechanic or automotive technician if: the P2167 code returns immediately after replacing the throttle position sensor or throttle body; you cannot locate the correct TPS signal wire without a wiring diagram and lack access to one; voltage testing reveals an absent or unstable 5V reference from the ECM/PCM, suggesting the control module itself is faulty; the vehicle is in persistent limp mode affecting safety; or you are not comfortable working with live electrical circuits. ECM/PCM diagnosis and replacement requires specialized scan tools and programming equipment that is beyond typical DIY capability.Frequently Asked Questions
Can I drive my car with a P2167 code?
You may be able to drive short distances, but it is not recommended. P2167 can cause the vehicle to enter limp mode, limit throttle response, cause rough idling, or result in stalling. Driving with this code long-term risks further damage to the throttle body, catalytic converter (from unburned fuel), or transmission if the drivetrain protection mode is active. Get it diagnosed and repaired as soon as possible.
What is Throttle Position Sensor E and how is it different from Sensor A or B?
Modern electronic throttle control systems use multiple TPS sensors on the throttle body to provide redundant position monitoring. Sensors are labeled A, B, C, D, or E to identify specific circuits within the assembly. Sensor E typically refers to a secondary or redundant sensor track within the throttle body sensor assembly. The ECM compares signals from multiple sensors simultaneously — if one reads out of range, a specific code is set for that sensor designation.
Will cleaning the throttle body fix a P2167 code?
It can, especially if heavy carbon deposits are physically preventing the throttle plate from fully closing. However, if the wiring and sensor itself are faulty, cleaning alone will not resolve the code. Start with an inspection and cleaning, perform the throttle relearn procedure, and then retest before assuming a replacement part is needed.
How much does it cost to fix a P2167 code at a shop?
Repair costs vary widely by vehicle make, model, and labor rates in your area. A throttle body cleaning typically costs $80–$150 at a shop. A standalone throttle position sensor replacement may cost $100–$250 including parts and labor. If the entire throttle body assembly requires replacement, expect to pay $200–$600 or more depending on the vehicle. Luxury and European vehicles tend to be on the higher end of this range.
Can a bad ground cause the P2167 code?
Yes, absolutely. A poor ground connection on the TPS circuit or a corroded engine ground strap can cause the sensor's reference voltage to read artificially high, triggering P2167. Always check and clean all engine ground straps and verify near-zero resistance on the TPS ground circuit before condemning the sensor itself.
