P1410 Code failures by brands

P1410 LEXUS, TOYOTA: EGR VALVE POSITION SENSOR CIRCUIT MALFUNCTION

Description of DTC code P1410

The EGR system (Exhaust Gas Recirculation) is designed to reduce the temperatures resulting from combustion and thus, the production of nitrogen oxide emissions is significantly reduced. In order to achieve its objective, the EGR returns the exhaust gases back into the cylinder so that they are burned together with the air/fuel mixture. This means that the exhaust gas burns more slowly.

The Exhaust Gas Recirculation has a valve that directly controls the Powertrain Control Module. When this valve is opened, the exhaust gas flows into the cylinders. Also included in this system is the EGR Valve Position Sensor (EVP), which tells the PCM what position the valve is in.

Diagnostic code P1410 OBD2 is set on Toyota and Lexus vehicles if the PCM finds a malfunction in the EGR Valve Position Sensor circuit.

Symptoms of fault code P1410

  • Check Engine lamp illuminates.
  • The engine runs unstable.
  • Engine temperatures increase during the combustion process.

Causes of OBD2 P1410

DTC P1410 OBDII is stored for one of the following reasons:

  • The EGR Valve Position Sensor circuit may have damage to its wiring.
  • The EGR valve could be stuck in the open or closed position.
  • The EGR Valve Position Sensor could be faulty.

Possible solutions of the DTC code P1410

The steps to follow to correct the P1410 OBD2 fault code are:

  • Consult the Technical Service Bulletins.
  • Check the EGR Valve Position Sensor wiring and circuit connectors and verify that they are free of any deficiencies caused by wear or burns. Repair as necessary.
  • Measure the EGR Valve Position Sensor circuit voltages and verify that they match those indicated on the vehicle's data source. If you find an out-of-range voltage, make corrections as necessary.
  • Check the EGR valve for proper operation. Check that it does not present blockages when closed or open. If such conditions are found, make the appropriate corrections.
