i checked the power to the tps Y/Wht, and Grn/wht... but how can i test the power from the tps Red/wht...while supplying power to the tps. the problem is that i cant get power past an idle in my car. When i step on the gas it falls on its face. i m getting a 43 trouble code on the computer. I have eleminated the fuel pump fuel filter. timing is awsome. i think im on the right track with the tps. i suspect that its the tps, the fuel pressure regulator, or icv... and suggestions or comments are both welcome and apprishiated



Also where can i find the right fuel pressure guage for this model??? and do i check it?

 

this must either be a good question 27 views and no replys lol

 

1. Make sure the ingition key is off then unplug the 3 pin connector from the tps.

2. Using a dvm, check the reference voltage from the ecm. Turn the ingition key to on and connect the positive probe to the yellow/white and the negative probe to the green/white wire. It should read approximately 5.0 volts.

3. If there is no voltage, repeat the test, but this time connect the voltmeter negative probe to body ground. If it now reads 5.0 volts, follow the green/white wire from the tps back to the pcm, check for breaks and poor connections.

4. If there still no voltage, follow the yellow/white wire back to the pcm for breaks and poor connections.

5. Next check the tps signal voltage. With the engine off, throttle fully closed and tps connector connected, connect the probes of the dvm onto the red/blue wire(positive probe) and ground (negitive probe). Gradually open the throttle valve and watch the tps sensor voltage. With the valve fully closed, the voltage should read approximately 0.5 volts. Now open the valve from closed to full open. It should increase smoothly to 4.8 volts. If the readings are incorrect follow the red/blue wire back to the pcm and check for breaks and poor connections. If the wire is good replace the tps.

 

yes its the signal from the tps i am haveing trouble with... with the connecter connected...how can i check thw voltage from the tps??? do i expose part of the wire??? how can i get to the copper to take a reading??? with the connector connected i just dont see how...

 

strip a lil peice of the wire. Come on doc.

 

thought so...just didnt really know im computer smart, but mech declined
