How To Correct P0488 Exhaust Gas Recirculation Throttle Position Control Range/Performance

Clean the blocked and clogged EGR and DPFE passages as regular usage can create carbon in those passages.
Replace the EGR valve if it is failed to operate only with vacuum pressure.

How do you fix P0409?

What repairs can fix the P0409 code?

Replacing the EGR valve.
Decarbonizing the EGR valve.
Repairing or replacing the wiring harness.
Replacing the EGR solenoid.
Replacing the EGR position sensor.

What does exhaust gas recirculation code mean?

Diagnostic trouble code (DTC) P0401 stands for “Exhaust Gas Recirculation (EGR) Flow Insufficient Detected.” This code means that the computer detects insufficient exhaust gas recirculation (EGR) flow in the system.

What does the p0403 code on an exhaust gas recirculation system mean?

The exhaust gas recirculation (EGR) system helps minimize nitrogen oxide gases coming from your vehicle’s exhaust. This is important because nitrogen oxide gases are very harmful for the environment in significant amounts. When your vehicle’s powertrain control module (PCM) detects a fault in your EGR system, the P0403 code could be set.

What does the OBD II fault code p2033 mean?

OBD II fault code P2033 is a generic code that is defined as “Exhaust gas temperature (EGT) sensor 2, bank 1 – circuit high”, and is set when the PCM (Powertrain Control Module) detects an abnormally high voltage in control circuit of the #2 exhaust gas temperature sensor (or in the sensor itself) that is fitted to the exhaust system of bank 1.

How does the exhaust gas recirculation system work?

The Exhaust Gas Recirculation (EGR) system is controlled by a vacuum solenoid. The solenoid is supplied ignition voltage. The Powertrain Control Module (PCM) controls the vacuum solenoid by grounding the control circuit(ground) or driver. The primary function of the driver is to supply ground for the object that is being controlled.
