i cant find the service connector for the tps anywhere. i have set it with a dmm and now want to check what the ecm thinks as i am idling extremely rich. the fsm says that it is between the maf and passenger strut tower, i have removed my maf and searched the entire engine harness with no luck. someone help asap.

 

out of curiosity, how do you propose to "check" what the ecm thinks?

 

well there are two ways of adjusting the tps, checking the ohms (1k-5k sweep) and the mazda check lamp deal. i have just set mine using the dmm method and would like to see what the ecm thinks of it. problem is i cant find the service terminals that are supposed to be behind the mass air flow meter and infront of the passenger side strut tower. all i have there is the idle dashpot, boost sensor, maf, lead for the injector resistor and a four pin check connector. i need to find that stupid three pin green plug.

 

The 1k-5k ohm sweep is fine. You're picking at a dead cow. Leave it alone if the sweep looks good. If the sweep isn't flowing well, replace the tps. Its best not to use a dmm for the tps btw, makes it hard to spot drops in the tps.

 

fully checked the tps, sweep is good but now after adjusting getting a check engine light. i think the top end is now reading too high. have a spare gonna check tonight.
