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 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’s the signs of a bad EGR valve?
What are the symptoms of a failing EGR valve?
- Your engine has a rough idle.
- Your car has poor performance.
- You have increased fuel consumption.
- Your car frequently stalls when idling.
- You can smell fuel.
- Your engine management light stays on.
- Your car produces more emissions.
- You hear knocking noises coming from the engine.
What is the code P1131 Ford?
Trouble code P1131 means that the powertrain control module has detected a lean condition for engine bank No. 1. Code P1131 can be caused by a vacuum leak, fuel injector problem, ignition problem or by a faulty oxygen sensor.
What does a stored code p0488 mean?
What Does Code P0488 Mean? A stored code P0488 means that the powertrain control module (PCM) has detected a discrepancy between the actual position of the exhaust gas recirculation (EGR) valve and the desired throttle position.
How can I reset the p0488 EGR code?
Connect the scanner to the diagnostic port of the vehicle and retrieve the stored codes and freeze frame data. Writing this information down may prove helpful later. Now clear the codes and test drive the vehicle. If the P0488 code is reset, accompanied by other EGR related codes, test EGR system efficiency.
What causes an illuminated malfunction indicator lamp p0488?
Variations between perceived EGR system performance and TPS position, over a set period of time, will result in a stored code P0488 and possibly an illuminated malfunction indicator lamp. What are the common causes of code P0488?
What causes a dpfe sensor to get clogged?
The most common cause is clogged DPFE sensor passages and EGR passages. You may also discover a faulty MAP sensor, EGR sensor, EGR valve, or EGR control solenoid. You might also find a broken vacuum line or faulty electrical wiring (or connectors).
