The P0406 code is the result of the exhaust gas circulation (EGR) sensor A having a high circuit voltage.
How do I fix code P0406?
What repairs can fix the P0406 code?
- Replacing the EGR valve.
- Repairing or replacing wiring harness as needed.
- Repairing poor electrical connections.
- Replacing the vacuum line.
- Cleaning excessive carbon buildup.
How much does it cost to fix a P0406?
With a P0406, more than likely the problem is with the EGR sensor component rather than the solenoid inside the EGR valve. On average this component (aftermarket) runs around $75.00. Replacing it will usually take around 1.5 hours of labor; not including diagnostics time.
Where is the exhaust gas recirculation sensor?
The EGR temperature sensor is usually mounted in the exhaust manifold or mounted near the EGR valve.
What is EGR valve position sensor?
The EGR position sensor detects the movement and position of the exhaust gas recirculation (EGR) valve pintle. The EGR pressure sensor detects exhaust gas flow through the EGR passage.
What is the code P0403?
P0403 is an OBD-II generic code that indicates that the engine control module (ECM) has detected the engine exhaust gas recirculation (EGR) circuit has malfunctioned. The ECM detected a short or open circuit in the EGR vacuum control solenoid or wiring to the solenoid.
What does P0405 code mean?
P0405 is an OBD-II generic code that the engine control module (ECM) detected the engine exhaust gas recirculation (EGR) sensor has went below its specification range. A short to ground of the sensor input to the ECM.
What is the code P0404?
P0404 is an OBD-II generic code that the engine control module (ECM) detected the engine exhaust gas recirculation (EGR) valve or sensor is out of specification range or its performance has gone out of specification parameters.
How do I fix code P0400?
What repairs can fix the P0400 code?
- Replacing the EGR valve.
- Replacing a broken vacuum line to the EGR valve.
- Replacing an EGR temperature sensor or cleaning the carbon off of it to repair it.
- Cleaning carbon out of EGR tubes to intake manifold.
How do I fix code P1404?
The diagnostic trouble code is P1404. Repair info: You can remove the EGR and clean the valve and passages thoroughly with brake cleaner or replace the EGR valve with a new or salvage part.
What can trigger an EGR code?
A clogged catalytic converter. Carbon buildup on the EGR temperature sensor. Faulty or lack of vacuum supply to the EGR. Electrical problems with the EGR circuit.
What causes P0400 code?
Diagnostic trouble code (DTC) P0400 code stands for “Exhaust Gas Recirculation (EGR) Flow Malfunction.” It is triggered when the flow of exhaust gas recirculation is lower than what the powertrain control module (PCM) expects.
