What does P0488 code mean?
What does P0488 code mean?
What the P0488 code means. The Powertrain Control Module (PCM) has discovered a problem with the rate of flow of the exhaust gas recirculation (EGR) system.
What does code P042E mean?
What does OBD-II fault code P042E mean? OBD-II Code Decreased engine performance is defined as a Exhaust Gas Recirculation “A” Control Stuck Open. EGR (Exhaust Gas Recirculation) systems are used to reduce the combustion temperature, thus reducing emissions.
What does P0405 code mean?
Exhaust Gas Recirculation Sensor A Circuit Low
What Does the P0405 Code Mean? Diagnostic trouble code (DTC) P0405 stands for “Exhaust Gas Recirculation Sensor A Circuit Low.” It denotes that the readings coming from the EGR valve position sensor show lower voltage levels than normal.
How do I fix code P0488?
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.
What can cause a P0400 code?
What are the Possible Causes of the P0400 Code?
- Faulty EGR valve.
- Clogged EGR passage.
- Disconnected or damaged vacuum lines.
- Faulty EGR-related sensor (e.g., EGR temperature sensor, EGR pressure sensor, etc.)
- Issues with the EGR control circuit, such as damaged wires or poor connections.
Can a P0405 cause a misfire?
When this occurs, you may notice misfires and even have misfire codes along with the P0405. This can occur on vehicles that use EGR “runners” for each cylinder.
What happens when a DPFE sensor goes bad?
When the DPFE sensor fails, it leads to poor engine performance and reduced fuel economy. The Check Engine Light might also come on the dash and your vehicle could fail an emissions test.
