I was watching Dr 914s walkaround of a D Jet 2.0 motor, and he makes a comment that the Cylinder Head Temp sensor causes a lot of problems, and can get wonky.
Is it possible for one to test out fine (2750 ohms) and then act bad? I have a strange syndrome where the car was running fine, but developed a rich syndrome very suddenly. Haven't had a chance to check it again, but it was almost new. TIA Rob |

I had one go out intermittently. usually if it goes "open" the engine will quit. The ECU needs to see some resistance.
Mine went rich because I was running a 1 k parallel resistor, so it was reading as if it was still cold. But better than sticking me on the highway, made it home and put a new one in. |
