Manifold Absolute Pressure (MAP) Sensor

34
There was no MAF signal for over 4 seconds while engine was running.

35

Idle Air Control (IAC) System

36
Transmission solenoid "B" has failed in the Off position which caused transmission to be in 3rd when 1st gear was desired, or solenoid "B" failed in the On position which caused transmission to be in 1st when 3rd gear was desired.

37

Brake Switch Stuck “ON”

38
The Torque Converter Clutch portion of the brake switch was open and caused the TCC to be inoperative..
39
The torque converter clutch portion of the brake switch was inoperative for 30 seconds causing vehicle speed ratio to be outside of its window of operation.
41
Cam sensor signal was not received by PCM for the last 5 seconds while engine was running.
