My 93 laser 1.8 5sp is currently having issues. It will randomly loose power, the RPM drop to about 2k, and then will only rev a few hundred rpm more before dropping back to 2k.
My father (a master mechanic and land speed racer) suggested it might be my TPS. I got out my multimeter and checked it, the input voltage is a whopping 11v and the idle signal voltage is 1.2v going up to 10.8v at WOT.
I read that the input voltage should be 5v and the idle voltage should be about 0.4v and WOT voltage should be about 4.75. Could this overvoltage be my problem and what can I do to fix the issue?
When the car looses power the CEL comes on but the only error code I get is a code 15 no signal to ecu from speed sensor. I'm really confused. Any help would be greatly appreciated. Thanks in advance.
