Good Day

I need some direction from you guys. You have been such a great help in the past 4 months getting my 95 650 t-r5 stablized. Well my tracks is blinking and my speedometer stopped working, so here are the codes
A1
142 Oil temperature sensor open circuit
114 Program selector open circuit or short circuit to supply
232 Speedometer signal missing
A2
212 Front HO2S signal
443 Three way cat. Efficiency
Im not sure if I should drive it. Please send HELP.


Thanks again

Rick

10/23/2015 Just check A3 and found no error codes.

 

Did you pull any codes from the A3? The speed sensor feeds into the ABS so you may be able to find more codes from the ABS.

As far as the possible faults for these codes -
The 114 suggests your PNP switch is acting up. Try the 'ol shifter row and clear the code to see if it resets
The 232 speed sensor fault can be connection to the vehicle speed sensor but the speed sensor also works through the ABS computer, the PNP switch multiplug and even the dash. Any one of those can be part of the cause...
Regarding the 212 and 443, they are likely related. Essentially they are saying the mixture is off and the controls can't compensate. Start by checking vacuum lines (including the stubs around the vacuum tree). It may be you have a bad O2 sensor - if your mileage has dropped off then it may be time. Another area is to check is around the intake (idle air/MAF/air filter etc)

 

I checked the A3 codes and didn't find any codes.
