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?
