Understanding the P1407 EGR System Malfunction Code The P1407 is a diagnostic trouble code (DTC) for "EGR Flow Insufficient Detected". This is a generic powertrain code, which means it applies to all makes and models of vehicles (1996-newer), although specific repair steps may vary depending on the model. In our workshop, we've seen the P1407

What is the P1406 Code? The P1406 code indicates an issue with the Exhaust Gas Recirculation (EGR) valve position sensor circuit. It is a manufacturer-specific code used by some makes like Ford, GM, and Isuzu. I've seen the P1406 code pop up quite often in our European car workshop, especially on Audis and Volkswagens with

Understanding the P1405 Engine Trouble Code The P1405 is a manufacturer-specific powertrain diagnostic trouble code that indicates a problem with the EGR (exhaust gas recirculation) system, specifically the differential pressure feedback sensor (DPFE) circuit. This code is triggered when the PCM (powertrain control module) detects an issue with the upstream hose of the DPFE sensor.

P1404 Code: EGR Closed Position Performance The P1404 is a diagnostic trouble code (DTC) specific to General Motors vehicles that indicates the Engine Control Module (ECM) has detected the Exhaust Gas Recirculation (EGR) valve is stuck open. In our workshop, we've seen the P1404 code pop up quite frequently, especially on European makes like Mercedes-Benz,

P1403 Diagnostic Trouble Code: EGR System Fault The P1403 code indicates a problem with the Exhaust Gas Recirculation (EGR) system. This is a generic powertrain code that applies to many makes and models. I've seen the P1403 code pop up quite often on various European makes in our workshop, especially Volkswagens, Audis, and BMWs. Just

Overview The P1402 diagnostic trouble code indicates a malfunction in the Exhaust Gas Recirculation (EGR) system. This code is generally defined as "EGR metering orifice restricted", though the exact definition may vary slightly between vehicle manufacturers. I've seen the P1402 code pop up quite often on various European makes in our workshop, especially Volvos, MGs,

What is the P1401 Code and How Urgent is It? The P1401 code indicates a problem with the Differential Pressure Feedback EGR (DPFE) sensor circuit. This code means the powertrain control module (PCM) has detected the DPFE sensor signal voltage is above the expected range. In our workshop, we've seen the P1401 code pop up

What is the P1400 Code? The P1400 code indicates a problem with the Exhaust Gas Recirculation (EGR) system in your vehicle. It is a manufacturer-specific code, so the exact definition may vary slightly depending on the make and model of your car. In our workshop, we've seen the P1400 code pop up quite frequently, especially

Urgency Assessment The P1237 code indicates a fault in the fuel pump secondary circuit, which is a critical component of the vehicle's fuel delivery system. While not immediately dangerous, this fault can lead to poor engine performance, stalling, or difficulty starting the vehicle. In most cases, it is safe to continue driving for a short
