Okay, here's the story. A few months ago I bought a 90 SC off of e-bay. Paid only $1300 so I thoght I was getting a good deal. A couple months after that, the car totally died, replaced cam sensor, crank sensor and DIS module to get it running again.
Now it's back to the same problems it's had ever since I got it. It runs alright, I guess (I don't know anybody in Austin who has one to compage). The check engine light just will not go off.
I pulled the codes and I get not one, not two, but six different failures all at once. These are the "key on" codes in no particular order (actually, the order I get them in)
51 - Coolant Temperature sensor circuit open
22 - Barometric Pressure Sensor out of range
53 - Throttle Position sensor out of range (high)
54 - Air Charge Temperature sensor circuit open
35 - EGR Valve Pressure Transducer/Position Sensor voltage out of range (high)
67 - Neutral Drive Switch circuit open
Now I know what all of those are except the last one, what is a neutral drive switch? Even without knowing that, I would think that not that many sensors would fail all at once. Other posts say that these computers often just point you in the direction of the failure. Well, the only think that connects that many components that I know of is the ECC itself.
I tried swapping a few sensors from my friend's mustang since the engines were similar, but the same problems were present on my car and no problems showed up on his. Now I only tested the air charge and BAP sensors, but I got the idea that they were working on his.
So....any ideas on what might be causing all these faults? I'm totally confused.
