The oil pressure sender is at the back of the engine, to the right (towards the driver's side) of the distributor. It's screwed into a 90ยบ fitting.

 

great, that should be fun to find...haha Thanks a lot! anything else to be worried about?

 

The oil pressure sender is pretty big...

 

Duntov and all,

I found this thread while searching for a solution to my ABS light on problem.

I' ve checked for codes and get:

27, 66, 86, 12, 25, and sometimes 26.

When I reset the light, turn off, turn ign. on. (engine off) the system does its self test and returns with the same codes. I can hear the ABS unit turn on and off, btw. I've checked the front left sensor resistance and it checks out ok. Some of the other codes are related to the hydraulic/electric unit.

I know there's a particular order with which codes to takle first, but don't know this order. I've attached the two pages applicable with the codes listed. This is from a user's manual for one of those code retrieval units that plug into the diagnostics port.

Please help - I'd like to get this thing working if at all possible (I like a challenge).

 

Um....my 1991 ABS system has not worked in 3 years due to a bad right front wheel sensor that I do not want to replace until I have to replace the bearing and cv axle as well. My point is my brakes are fine and dandy...I just do not have 4 wheel ABS. I have bled my front and back brakes whenever I replaced the calipers and front lines and rear cylinders........Again my brakes are fine and dandy just no ABS.

 

the only other problem i have ran into on the s-10 blazers is the oil lines that go from the engine to the oil filter tend to leak last i checked for pricing (mine currently needs them) they are about 40-50 dollars.
