Picked up a free 96 Ranger (3.0L V6) this weekend. Has some issues but it does run so that's a start. Two things I could use some advice on:

1) Where is the flipplin PCV valve located on this engine?? I've searched all of the multiple Ranger forums and have come up cold. Been told its on the driver's side of the engine on the back but can't seem to locate it.

2) The truck had a CEL on when I got it. Brought it to Autozone to have the codes pulled and got multiple O2 sensor codes. O2 Sensor Circuit Malfunction codes for each of the three O2 sensors (P0130, P0136, and P0150 I believe if I remember correctly). Also got an 02 Sensor Heater Circuit Malfunction for one of the sensors as well.

Sounds like an electrical issue to me. Haven't had the time to check the wiring for the O2 sensors but I'm assuming they all meet up somewhere. Anyone else had a problem like this? Wondering if the O2 sensor harness got messed up somehow. Truck runs fine and idles well so it's not acting like the sensors are all messed up.

Any ideas ppl?

 

wait, where do you get a free 96 ranger from? ha

 

I must have the luck of the Irish... which is odd b/c I'm not Irish...

anyway. anyone have all three sensors have circuit malfunctions b4??

 

i dont know about the circuits... but the PCV valve is right on the back of the intake manifold, its a black rubber elbow that goes from the intake down.

 

found the pcv np lol after realizing it has a right angle attached right to it. thanks guys!

anyone have a circuit diagram for the o2 sensors?? i know i need to get a good manual but i just havent had time yet.

 

Not sure on the 6cyl, but on my 4cyl there was a 15 amp fuse in the power dist. box in the engine compartment that was blown. Hope your fix is as easy.

Regards,

Bruce

 

any idea what number fuse that would be??

i cant believe all three 02 sensors would have circuit malfunctions around the same time unless it was an electrical issue or one sensor was actually bad and was messing with the others...

any1 got a circuit diagram for the 02 sensors?? i saw it online somewhere but cant remember now

 

nvmnd i got the wiring diagram

 

the o2 sensor CELs turned out to be just a blown fuse. the 15A fuse located in the engine compartment.

 

Thats good, now post some pics of your Ranger
