1992 Buick Riviera 6 cyl Front Wheel Drive Automatic 148000 miles
Occasionally, the car stalls at red lights, or just won't go. As far as not wanting to go anywhere, I'm assuming that it would be the transmission possibly just badly in need of being serviced (I don't know how long it's been, I just got the car). I did pull a few trouble codes:
21 - TPS voltage high - I know how to adjust that.
24 - Vehicle speed sensor (VSS) - open or short circuit
problems or park/neutral switch circuit problem - could this cause the car to not move from a red light? I didn't think that this would be an electronic transmission.
- Manifold air temperature (MAT) sensor - signal voltage is low or high
- Vacuum switching valve circuit open or shorted to ground
- ATS sensor - signal voltage is high or low
41 - Cam sensor (CAM) failure
- Cylinder select error
- Tach input error - no reference pulses during engine run
- Electronic spark timing (EST) circuit - open or shorted to ground during engine run
- Direct ignition system (DIS) fault - bypass circuit open or shorted to ground during engine run
- Ignition system fault - loss of 1X Reference Pulse signal.
Mainly I'm interested in 24, but if you have any suggestions abut 41, please let me know. Thanks
have the same problem?
