  2. Replacing a corroded connector to the EGR vacuum control solenoid.
  3. Repairing the wiring shorted to the EGR vacuum control solenoid.

What causes a P0403 code?

Here are the common triggers of the P0403 code: Faulty EGR valve. EGR control circuit issues, such as damaged wires or poor connections. An issue with the PCM.

What does EGR circuit fault mean?

A faulty EGR valve can cause problems with the flow and operation of the EGR system leading to performance issues including a reduction in power, reduced acceleration and decreased fuel efficiency. EGR valves can become stuck ‘open’ or ‘closed’ due to a build-up of soot particles, carbon deposits and dirt from fuel.

Where is the EGR solenoid located?

It is normally attached to the engine block with a nut and is close to the EGR valve. The solenoid can be located by following the rubber vacuum hose from the EGR valve on the back of the engine block to the solenoid. Replacing the EGR solenoid can be done in just a few minutes and you can save time doing it yourself.

  1. Replacing the EGR position sensor after the wiring is checked to be okay.
  2. Repairing the wiring short to the EGR position sensor or connector signal return.
  3. Repairing an open in the voltage reference to the EGR sensor.

What does exhaust gas recirculation control circuit range performance mean?

Diagnostic Trouble Code (DTC) P0404 stands for Exhaust Gas Recirculation Circuit Range/Performance Problem. It could mean that your EGR valve isn’t doing what it’s supposed to do in specified parameters such as being fully open when it should only be partially open.

What does a vacuum solenoid do?

Vacuum solenoid valves, also known as Electro-pneumatic pressure converters, Electric switch over valves or Boost control solenoids are used to control many systems of engines by controlling actuators – for example, variable geometry of the turbocharger, EGR valves, various bypass or throttle valves etc.

How much does it cost to replace the EGR sensor?
