The P1406 trouble code typically relates to issues with the EGR (Exhaust Gas Recirculation) system, specifically indicating a problem with the EGR position sensor. Other sensors that could potentially contribute to this code include the throttle position sensor (TPS), which affects the EGR operation, and the intake air temperature (IAT) sensor, which can influence engine performance and emissions. Additionally, issues with the vehicle's mass airflow (MAF) sensor could impact the EGR system's functionality. Checking these sensors and their connections may help in diagnosing the underlying issue.

What is Code p1406?
This code indicates a problem with the EGR valve's pintle position. The EGR Valve's pintle could just be stuck in which case the problem could be fixed by cleaning the EGR valve. If the EGR valve is electronically controlled or cleaning the valve does not fix the problem, you will most likely have to replace the EGR Valve. Keep in mind that the EGR valve relies on inputs from other sensors to determine the pintle position. If one of these other sensors is not operating correctly, it could be giving you a false P1406 error code.

The P1406 code on a 1996 Oldsmobile Cutlass Ciera 3.1 is the code for the EGR pintle position circuit. I know this because it was my question initially and we bought a code reader to check the problem. It is a factory specific code, so the answer is quite specific. Good luck !
What it means code p1406 in a izuzu rodeo?
Code P1406 in an Isuzu Rodeo refers to an issue with the Exhaust Gas Recirculation (EGR) system, specifically indicating a malfunction in the EGR temperature sensor circuit. This could be due to a faulty sensor, wiring issues, or a problem within the EGR system itself. It's important to diagnose the exact cause to ensure proper emissions control and engine performance. Addressing this code typically involves inspecting the EGR system and its components for faults.
