| Post subject: | MAP_Called the Air Pressure Sensor or Air Intake Sensor |
Nice to be able to log in again!! Missed you guys. I just received what I thought was a MAP Sensor to replace one that keeps throwing codes. In the manual, the part I thought was called a map sensor is referred to as a Air Pressure Sensor. The company sent me a Air Intake Sensor that isn's even close and are insisting that is what I ordered. It is supposed to throw a MAP sensor code if it doesn't work. Is there such an animal in my CRD? It has two holes for mounting, a narrow sensor that is only 1/2 inch long, three male prongs in a triangle configuration. Thinking of just rebuking the visa charge and moving on. Jim |

I remember seeing the fiche on a website. If you have the web addi that you used to check, that may help me deal with this order and future orders...interesting how the parts guy wouldn't even consider that his database wasn't accurate. I talked with a fellow today who has similar experiences with his Ford Truck. He doesn't understand why the mechanics and parts people don't stay on top of the forums. This is where the accurate information is. Jim |

This is where the accurate information is. Jim You will find it here, there is one specific page which show it incorrectly drawn. I believe the image and name was switched, but I think the part number was still in the right place(I think). http://colorado4wheel.com/allmanuals/Jeep/KJ/ I believe both the 05 and 06 parts fiche have the error, forgive me but I don't feel like pulling up the specific page it is on. |

this is great. Jim It is call air intake temp sensor and the part #is 68031593AA. and it cost $82.57 and I have seen it as high as $95.00. |

| Post subject: | Here is the Service Manual Page on the Boost Pressure Sensor |
On page 4355. Section 14-100 Fuel Injection 2.8L Diesel BOOST PRESSURE SENSOR DESCRIPTION The boost pressure/intake air temperature sensor is mounted to the top of the intake manifold. The sensor allows the ECM to monitor air pressure within the intake manifold. This sensor is also used to monitor the intake air temperature. OPERATION When the intake manifold pressure is low sensor voltage output is 0.25-1.8 volts at the ECM. When the intake manifold pressure is high due to turbo boost, sensor voltage output is 2.0-4.7 volts. The sensor receives a 5-volts reference from the ECM. Sensor ground is also provides by the ECM. The ECM uses boost pressure combined with intake air temerature to determine the volume of air entering the engine. DIAGNOSIS AND TESTING - BOOST PRESSURE/INTAKE AIR TEMPERATURE SENSOR If the boost pressure sensor fails, the ECM records a DTC into memory and continues to operate the engine in one of the three limp-in modes. When the ECM is operating in this mode, a loss of power will be present, as if the turbocharger was not operating. The best method for diagnosing faults with the boost pressure sensor is with the scan tool. Refer to the Diesel Powertrain Diagnostic Manual for more information. |
