Have the following codes on my '95 non turbo N/A volvo 850. Gor the codes from the code box in front of engine. Tried resetting codes and none reset. No CEL are flashing. I am getting ****ty gas mileage and brakes do feel weak when pushing them. Also currently using a jumper for the fuel pump relay. Thanks for any help
A1 port: 223, 114
A2 port: 343
A3 port: 142, 213, 214, 311,312,314
A7 port: 113,122


A1 port : 223 is low tps reading. Not sure what the 114 means

A2 port: 343 fuel pump relay. I need to find another. Had someone replace the caps, worked well for a week. Tried to fire up today no luck. Can hear pump priming with relay in though. Put in jumper fires up no problem

A3 port: speed sensors on all the wheels? and brake pedal switch

A7 port: not sure

 

Does it idle okay?

 

check out volvotips.com on how to interpret OBD1 codes and how to do further tests

 

I bought a replacement fuel pump relay, cleaned my throttle body and tps sensor. Did a battery reset again. Now I am only left with the codes from the A3 port. The ABS system.

 

Inspect and clean the wheel sensors.

 

thats the plan. will try to begin today

 

+1 on tonyfr's comment - inspect both the sensor and the inside of the wheel hub, particularly if you have had a torn CV boot. Sometimes they can throw grease on the inside of the hub which messes with the speed sensors.
