You now say you have a bad resistor in the TPS? Wasn't that a new one?

Ok so I have a strong power and strong ground just somewhere whether it be I just have bad luck or the sensors I buy just suck and the signal is bad....I do have a bad sensor seal and in the process of searching for a new one

GaryDoug

Try removing the sensor and, while it is hooked up to the meter (with pcm and ignition), manually turn the actuator on the sensor (as if the throttle is moving). See if that changes the voltage.

Ok I'll have to try it when I get home I'll be at work till midnight

The end of the shaft is flat. A rectangular hole in the sensor fits over the flats. There is a foam seal that inserts in the boss in the throttle body, before the sensor is inserted.

Ok so I did the test of removing the sensor with everything on and still no change could I have really got another bad sensor

GaryDoug

When you say you did the test, which test do you mean? Try this ohms test where you connect the black meter lead to the black ground wire of the tps, and the red meter lead to the dark blue wire of the tps. Then you measure ohms while turning the sensor with a screwdriver in the slot. For this test, use the 20k range. Also measure the ohms from the black tps wire to the gray tps wire (while not turning it) so we know the total resistance.

The ohms never changed from 1 . On the 20k ohm measurement same with the grey to black

GaryDoug

Sounds like the ground pin on the sensor is bad. To confirm that, measure ohms from the gray wire to the blue wire. It should vary with the setting of the slot, probably from zero to 4 or 5 kohms

Then check the connector again by putting the meter to the 200 ohms range and checking all wires from the ends to the terminals. The 3 readings should all be about zero ohms.

I show a 1.7ohms and 4.8v between blue and grey

GaryDoug

Please do the resistance test (blue to gray on the tps) with all wires disconnected from the tps. If still under 1000 ohms, I think we can't trust the meter (or the tps).

It showed 1551 for about a second and then went back to 1

GaryDoug

The dilemma in which I find myself is not knowing if we can trust the meter. Normally I would just suggest buying a new tps, but that costs money and I can't be sure.

To check the meter, do this: unplug the engine coolant temp sensor on the driver side head and measure the resistance from the pin on the sensor to the block. Should be about 3000 - 10,000 ohms. if that is ok, then we can trust the meter and replace the tps.

1880 for the ect

Unless it's around 90 degrees F or more where you are measuring now, that can't be accurate. Time for a new meter.
