Depending on year, make, and model, DTC P0406 may have number of causes. Here are some of the most common. Sensor Fault – Because it is constantly subjected to heat from the exhaust, internal electrical faults are a common occurrence. Replace the sensor, clear the code, keep driving.

The check engine warning light can come on for a faulty oxygen sensor, a damaged manifold intake sensor, or a poor EGR valve replacement. The check engine light illuminated due to the EGR valve will come on almost as soon as the vehicle’s central computer, the electronic control unit, notices that the EGR valve is faulty.

The Exhaust Gas Recirculation (EGR) Temperature Sensors are variable resistors that measure the temperature of the exhaust gas at the inlet and outlet of the EGR cooler. The Engine Control Module (ECM) supplies 5 volts to the EGR temperature sensor signal circuit and a ground for the low reference circuit. EGR Lift Sensor Abnormal: 523541-3: EGR Lift Sensor Abnormality - High: 523541-3: EGR valve position sensor voltage OORH (shorted to B+) 523541-4: EGR Lift Sensor Abnormal: 523541-4: EGR Lift Sensor Abnormality - Low: 523541-4: EGR valve position sensor voltage OORL (Open or grounded) 523543-2: APP Sensor Error: 523544-3: Air Heater Circuit.

On my old mk1 1.2htp, which is a petrol engine, the sensor was part of the egr valve, so you changed both together. It may be different for a 1.6 cr diesel. Is that the engine where the egr valve is in a pig of a place up at the back of the engine and takes best part of a day to replace?. An EGR valve that does not close completely will result in a more noticeable power loss. The consequence of a valve failure is a failure of the entire exhaust gas regulation system, which is accompanied by a light flap on the dashboard, at the head of which the check engine lights up. The signs of this are usually: "floating" idle speed.

It has sensors before and after the Cat, and if the cat is working, the sensor readings confirm this to the ECM. And if the Cat isn’t working, the sensors say this to the ECM too, and if they keep saying the Cat isn’t working, the ECM will turn on the check engine light. When your new cat was installed, the Cat shop probably reset the ECM. ️ ️EMISSION TEST TIME?
