Rc0603jr 0727rl Smd Resistors 0402 Code High Voltage Smd Code Diode A code p0402 most likely means one or more of the following has happened: the dpfe (differential pressure) sensor is faulty and needs to be replaced. there is a blockage in the egr (most likely carbon buildup) the egr valve is faulty. the egr valve may not be opening due to a lack of vaccuum. If you see trouble code p0402, it means that your vehicle’s computer system has recognized, through the differential pressure sensor, that the egr has excessive flow. unless the issue is a faulty sensor, excessive flow could affect the performance of your engine. a faulty sensor may still cause your egr valve to open or close improperly.
Rc0603jr 0727rl Smd Resistors 0402 Code High Voltage Smd Code Diode For Follow the following steps to diagnose the p0402 ode: use an obd ii scanner and record the freeze frame data in order to confirm the existence of the p0402 code. after inspection, clear the codes and perform a test drive. if the p0402 code returns, then move for further inspection. inspect the vacuum hoses for damage or blockage. Code p0402 is often set when the egr monitoring criteria are excessively triggered—triggers include too much manifold pressure change, too much oxygen sensor change, and too much egr temperature change. code p0402 is often set when the egr monitoring sensors are still showing egr flow after the egr monitoring tests are complete. P0402 code definition. exhaust gas recirculation flow excessive detected . what the p0402 code means. p0402 is an obd ii generic code that the engine control module (ecm) has detected indicating the engine exhaust gas recirculation (egr) valve is flowing too much recirculated exhaust gases when it is commanded to open the flow of gases into the intake manifold. The p0402 diagnostic trouble code (dtc) for ford vehicles indicates that the exhaust gas recirculation (egr) system is detecting excessive flow. the egr system is responsible for recirculating a portion of the exhaust gases back into the engine's intake manifold to reduce combustion temperatures and emissions of nitrogen oxides (nox).

The p0402 code stands for “exhaust gas recirculation ‘a’ flow excessive detected.”. it’s logged when the pcm detects excessive egr. some possible triggers for the code include a faulty differential pressure sensor, blocked egr passages, and a failing egr valve. symptoms to look out for include an illuminated check engine light. Check exhaust catalyst: inspect the exhaust catalyst for damage. repairing or replacing a broken catalyst may be necessary to fix the p0402 code. address egr temperature sensor: make sure the egr temperature sensor is functioning correctly. replacing a faulty sensor can be important in addressing the p0402 code effectively.
