Afterward the speedometer and tachometer would not work. Tried the trip odometer reset trick, never saw it go into self test. Do the engine and wheel speed sensors send signals to the ECM? I also had to manipulate the relay box to R2 the ECM. Is it possible I've screwed something up there? This thing is driving me nuts.

sensor is bad. I've determined that the sensor is part of the pcm. Where is the pcm located in the car? I think it's next to the relay box in the front left of the engine compartment but I'm not sure. There are two other codes displayed. One is the o2 sensor and the other is the coolant sensor. Could the pcm be at fault for those as well?
