| Post subject: | MAP sensor question |
I need to know whats on the pin for the MAP sensor ? The reason is i need to determined of the MAP sensor for the wifes KJ is faulty or not, before I buy another. There is 4 wires for the MAP sensor, I guess that 2 are voltage {12v} and the other 2 are a small voltage change with the engine running. If this is right , which wires are doing what? By the way I still have the engine check light is still on, i took it to a local NRMA mechanic and he put a scann tool on it and read NO codes, But still the engine check light is still on. I did clean the MAP sensor with engine degreaser and a cotton cloth with a metal paper clip to clean the copper looking element in the MAP sensor, but used care Allen |

The guys over in the "CRD Lovin' That Torque" section will have an answer for you. I do know that there are some cleaning agents that they don't advise, not sure if degreaser is one of them. I used paint thinner and a tooth brush. |

Done this a few times, comes out spotless, like new. |
