Hi Guys,
So when i had a intermittent fault where the EML would come up and my TPS voltage was low. When the EML was on, the car would idle high, and VTEC wouldn't kick in; it would just run like poop. You could clear the fault code and the throttle would become very unresponsive and the car would jerk. I could sometimes clear the fault code and give the car a hard drive and it would fix this and VTEC would be fine. Every now and then it would come back and the above would fix it. I measured the TPS voltages with a multimeter and got 4.45V WOT and 0.41v Closed which seemed fine.
Recently clearing the EML wouldn't fix this so I purchased the K Tuned Hall Effect TPS from Tegiwa. I fitted it and I now get 0.59 closed throttle and 3.57 WOT. The car has no fault codes now. VTEC is back and tbh feels like it pulls harder then ever. The car now kangaroos at low revs between 1k-3k as I let off the throttle and have to use the clutch a bit and floor it to gain life back, but the car will not stall itself. I have cleaned the TB out and it was oily. I have taken my induction kit off and manually closed and fully opened the throttle and it still gives the same voltage readings. I have also moved/turned the TPS to give the lowest voltage reading position. I have reduced the grub screw to try let the throttle close more but it is fully closed. I can't get it to move closer to the grub screw and it looks like the throttle wheel, (my mechanical terms aren't the best my bad the part the cable is hooked into), hits the throttle body when fully open. To me the throttle valve inside is as open and closed as it can go anyway just the voltages aren't coming back as they should.
Tonight I am going to try tighten the throttle cable as it does seem slightly slack, and Ill take a look at the IACV and see if it needs cleaning.
Is there anything else I am missing??
My car engine spec is in my signature.. I have a unichip piggy back ECU not a Kpro know people have fitted this TPS without Kpro. I believe the TB hasn't been mapped to the car since purchased and fitted but would that really be the reason for all this?
