Hello Fellas, 2 days ago I had an issue with my VTEC, I have a B16A SIR II swapped on my hatch. I take off the throttle for cleaning, I disinstalled the TPS and MAP sensors, when I when you put everything in its place appeared the code 7 (tps) and was out of calibration, a friend of mine helped me to calibrate it, TPS was poorly calibrated (0.47), then I went to drag race when I was burning tires using launch control and I hear the vtec activated but then I repeat the burning tires and rpm not go up to 4500 rpm and vtec did not activated. No code appeared and the oil level was correct. Yesterday I changed the solenoid for one of B18C and then calibrate the tps again to 0.5 and the engine feels good

Being miscalibrated TPS could have caused the vtec not activate and revolutions do not go up in 4500?

Please if someone had the same issue before, help me out!!!! It is very confuse.

Thanks in advance!!!!

 

Replacing the tps is tricky and must be done carefully to engage the mechanical linkage correctly. 0.5v closed and 5.0v wide open, you must check it every time you remove or replace one.

 

i thought it was 4.5v wide open? uh oh..

 

thanks itsmejto!!!!!!

Do you think that bad calibration on TPS was the cause of my problem????

 

yep

 

Ok I will go to drag race tonite and I will expect that my engine runs better

Thank you very much
