Attention: TDR Forum Junkies I have been experiencing variable throttle response on my 01. 5, 5 speed for a couple of weeks. Ninety percent of the time the response seems fine. Then it has spells of "dead pedal," actually, the pedal the remains weakly responsive. I did the odometer codes and have these:
PCU: 1693: Fault in ECM and / or Companion DTC set in ECU/PCM
ECU: 1488: Sensor supply for ECM is Low and,
Aux. 5V sensor feed sensed less than acceptable
I put in a 50 hp Diablo Puck about 3 months ago, a 4inch exhaust, and the lift pump is down on the frame. I pull 9,600 LBS. Fuel pressure, EGT readings (post) have remained in the proper range,the boost may rarely get over 22 . The batteries are new, and I'm about to turn 100,000 miles.
I have the Geno's guage writeup on the ECM/PCM hookup. It shows some 5 V in/outputs. I am also pretty ignorant on computer controlled stuff. I would appreciate some guidance.
