SOURCE: engine service light

The DPFE (Diferential Pressure Sensor)sensor is usually mounted on the engine and is connected to the pipe that runs from the exhaust manifold to the EGR valve with two rubber hoses. When the sensor goes bad, the Check Engine light comes on and typically sets any or all of teh following fault codes: P0171 & P0174 (lean codes), and/or P0401 (insufficient EGR flow). Nine out of ten times, the fault is not a bad EGR valve or a vacuum leak, but a bad DPFE sensor. A replacement costs about $112 at Ford, or about $48 at an aftermarket auto parts store.I hope this helps.

SOURCE: Code PO 299

If you are sure that is the right DTC, P0299 is not a generic OBD-II DTC (Data Trouble Code), and it is a manufacturer specific trouble code that is for an under-boost problem, and it would most likely be related to a problem with a turbo-charger.

SOURCE: engine light on 2002 Explorer. engine code P1400

This may have to do with a bad wiring. Check all the wiring associated with EGR operation. Whenever a computer throws a code about high or low circuit voltage, it is usually attributed to abnormal wiring.

Steam cleaned engine now have po 237 fault code

Hi Carl, Seems you have some condensation in the turbo boost circuit. Have it blown out with compressed air and hope that it clears the fault. The fault code refers to low signal turbo boost control. It's not a good idea to have vehicles with electronic systems steam cleaned. Regards John

The P0238 code relates to a Turbo Boost sensor pressure High. The P0106 is a MAP sensor code and could be caused by a bad or loose hose to the MAP sensor and can cause the P0171 which is system to lean code. The P0297 is a vehicle overspeed code. Hope this helps you some.
