I was replacing the TPS on my H22A and when I tried to set the voltage, even with the throttle fully close I was getting 3.1V and WOT 5V.

So I test the wires and the GREEN/WHITE STRIPE wire has 3V on it all the time. Isn't this suppose to be the GROUND??! So I am wondering if its okay to Ground this wire to the chassis or the ground on the Thermostat housing...

BTW, with the GREEN WHITE wire grounded it did give the correct reading on the multimeter... So what should I do? Would I damage the ECU if I grounded the GREEN WHITE wire?

 

 

Was the tps working ok before u replaced it? Something that got me stumped for a long time was that it has to be in a special groover when u put the tps in. U got to put it in, then turn it, then if u let go it should slowly slide back to unwind, so make sure u have it in the groove it needs to be in first. The middle wire of the tps should be signal wire, should be .45-.5V at idle, the one to the right should be 5 volt constand and the one on the left should be ground wire.

 

Nevermind, I figured it out - the story goes - I bought the motor from jdmspeedlab on Ebay who is like a middleman for that POS Osaka Japan in Canada - (Oh yeah, look out for my review of this entire sale soon with pics) - The harness came cut in all different places so since I was low on cash I just "rebuilt" the entire harness with new wires and rewired all the sensors completely. Now let me tell you that although I went for a while to college for Electronics Engineering I ... this was still NO WALK IN THE PARK.

Well somehow I got the ground and signal wire for the IAT sensor mixed so it was throwing 3.1V on the GRN WHT sensor ground - to make a long story short, last night I spent over 6 HOURS fixing the glitches in the wiring and straightening it out. TPS started reading correctly and is in the 0.5V to 5V range now!

Started it up ... NO CHECK ENGINE LIGHT!!!

Now for the axles and shifter to go in over the weekend ...

 

Good job for figureing it out dude! Pm me if u need any help on the axles and shifter.

 

Sure, Thanks! Well I thought I would get to install the axles this weekend but since they are Stage 3 DSS, now I need to remove the entire hub assembly to install the DSS Hubs (since their Stage 3 axles have different splines) and get the wheel bearings pressed in.

So I guess I will just install the shifter over the weekend and remove the lower hub assembly so that I can take it to the local machine shop and have them press the bearings into the hub and install the hub onto the assembly. Can't wait to take this baby out on the street!
