Code 43 - Starter Signal

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.
