Ya i got all that but what do they mean? Im drivin a 91 turbo w/5sp now i dont have speedometor cable hooked up cause needs to be fixed which i figured is 42 but not sure and i have no idea what 43 means by the description.

Can anybody tell me where the vehicle speed sensor and/or show me a pic of where it is.
|
If its the one I'm thinking of then its on the back of the instrument panel, the TSRM should have something on it in the cruise control section.
Good luck. |
I looked but no luck theres not a good picture of where it is. My ecu threw a code 42. and My speedometer quit working. Where does a ecu get a signal of how fast the vehicle is going. I dont have ABS, whats the purpose of this sensor.
|
Well if your speedo cable is broke then it wont spin the speedometer and then it wouldn't send the signal to the speed sensor, I could see how that could fool the ECU in thinking the sensor was bad.
I think the sensor is mainly for the cruise control. It should be labeld on the back of the instument panel. Good luck. |
