Re: 1995 cadillac deville

TPS code should be included in the DIC database. I think only direct stream data is obtained only from the diag connector and not from the DIC.

To test the TPS sensor, it's very simple, don't need a pinout. It has 3 pins, usually in this order: GND, sig, 5V-ref. From GND to 5V-ref you should have 5V. GND is the lowest voltage. The other pin is sig. Easy to figure out.

Backprobe GND and sig with your voltmeter. (Connector should be connected in this test.)
Turn key to ON. You should have less than 1V or so at closed throttle and 5V at full. Voltage increasement should be steady and smoothly.

The 2nd method is test resistance between gnd and sig of sensor w/ harness disconnected and see if it increase smoothly.

A Windstar without having the check engine light is not a real Windstar.
