ok so today i decided to do the paper clip trick on my lude to diagnose what code it was throwing.

this is from a 93 prelude Si automatic with an h22

so i got code 7(tps), the one i have on the car is kinda broken. i have another one here, so do i have to switch it out and and calibrate it with a multimeter?

second i got code 10(intake air temperature) this i dont know where it is, i

searched but came up with very little information that didnt really help me

out. does anyone know where it is?

third code is 21(Variable Valve Timing & Valve Lift Electronic Control (VTEC) Solenoid Valve)

does this mean i have to connect vtec, since mine is not wired up yet.

and last code is 23(knock sensor) this one i know where it is, and the guy that sold me the engine told me about it, that it need it to be repalced so i was aware that i was going to get this code.

can someone help me out with codes 7 and 10 please. I searched but couldnt really find much inforation about them.

thanks.

on the driver side of the intake manifold there is a white plug. thats the intake air temp.
as for the tps just swap it out. had the same codes, i just swapped the tps with a blox racing one.

you need a wire tap for the tps signal wire. san jose is a little far but i can help.
