P2141 code definition

Exhaust Gas Recirculation Throttle Control Circuit Low

What the P2141 code means

P2141 is an OBD-II generic code for the engine control module (ECM) detecting the exhaust gas recirculation (EGR) control valve circuit is low. This typically indicates a short or an open circuit causing a low voltage return.

What causes the P2141 code?

  • The engine control module (ECM) controls the EGR valve function with a control valve and monitors the feedback voltage from the valve for problems and sets code P2141 if the return voltage is below specifications.

  • The EGR control valve is shorted internally to ground.

  • The EGR control wiring or valve has an open circuit.

What are the symptoms of the P2141 code?

  • The Check Engine Light will be illuminated and the code is set in the ECM memory as a fault. The light will stay on unless the problem goes away for more than three running cycles.

  • The EGR may not operate and can cause the engine to ping or pre-detonate the fuel at the wrong time.

  • The vehicle surges or bucks on light acceleration.

How does a mechanic diagnose the P2141 code?

  • Scans for codes and documents the code in the ECM, and then looks at the freeze frame data for failure

  • Checks the EGR valve control wiring and connection for loose or corroded connectors

  • Checks the control valve for shorted or open windings

  • Follows the manufacturer pinpoint tests for the diagnosis and replacement of the EGR control valve

Common mistakes when diagnosing the P2141 code?

  • Clearing ECM memory codes before checking the freeze frame data for the main failure problem, so the failure may be duplicated and repaired

  • Failing to clear the ECM codes after the codes are fixed

  • Replacing the EGR control valve without verifying the valve has a problem

How serious is the P2141 code?

Code P2141 is a code indicating the EGR system is inoperative and will cause the engine to have pre-ignition problems. This can lead to internal engine damage over time if the vehicle is continued to be driven with the problem happening.

What repairs can fix the P2141 code?

Additional comments for consideration regarding the P2141 code

Code P2141 is for a code that may be used on gas and diesel engines and may have different meanings for different manufacturers. Make sure to use the pinpoint tests for the manufacturer and code you have received. Some vehicles use the code as a signal for a throttle control problem, while others use it to signify an EGR control problem.
