my b20 swap is throwing code 7. I know this is throttle position sensor.
i took the tps off to clean the throttle body before i built the engine, could this have caused the problem, i have tried adjusting it but the code just keeps coming!
Any ideas?
 
There is a fine adjustment on these. You need to measure the voltage to set it correctly. With throttle closed you should have a reading of roughly .45volts and at WOT you should read 4.5-5.0volts. Car does not need to be running just ignition on to get a reading.
 
When it comes to voltometers I'm abit lost. Could you please explain the proccess. Thanx
 
Hey, I had this issue with my ek9 before, It first started with the throttle getting slightly stuck when coming to a stop at the lights (rpm holding at 2000 ish) so I thought I had to adjust the throttle cable a bit and slightly loosened it thinking it would shut it easier, and at the same time sprayed the hell out of the spring mechanism with wd40. still did it so I loosened the cable some more, and it Threw the engine code 7 on me. after that I was a bit lost, then took the intake off and cleaned the throttle plate with TB cleaner, and all was sweet, re adjusted the cable to the right tension and no more fault code either. So check to see if your throttle cable is set to the right tension. shouldnt be too loose or too tight.
 
have tried that, and i did clean it all just before i put it together so im pretty sure its the tps! just dont know how to volt check it!!
anyone?
 
Have you got a multimeter available to you? You can pick up a 10-15euro one that will do the trick.
 
easy. usually it should have 3 pins on the connector. find the signal wire. which would vary as u open and close the throttle body. take one of ur leads and touch a bolt or metal part of ur engine or the negative battery terminal. and the other lead, start touching the pins with out damaging them. and you should see a reading. set ur volt meter to the V simbol with the parallel lines above them. not the wavy ones. that would be a/c voltage. cars work with dc.
hope this was a help.
