Well Im back again. Turns out that my Vtec wasn't kicking because the TPS wasn't hooked up correctly. Its a long story so i'll spare you, but rest assured, its working now.

When I got the TPS correctly hooked up, my car stopped throwing the Crank angle sensor code and the vtec pressure switch code. Drive the car, vtec works! I'm so freaking excited. Drive the car around here and there for the rest of the day, works fine. Go to hang out with some friends, vtec stops working...so I'm like what the hell???!

Check which codes its throwing, and now its throwing the crank angle sensor AGAIN, along with knock sensor (which it should have been throwing frmo the beginning, since there isn't one hooked up). Whats weird is that if I let the car sit for a few hours (3+), the crank angle sensor code will go away (almost like the heat is getting to the sensor). When the car runs at low temperatures (~5 minutes after starting up), Vtec works FINE. But after driving for about 20 minutes, vtec just stops working entirely (and it starts throwing crank angle sensor)again....think I need to replace my whole distributor or what?

 

Any ideas??

 

What year is your car ?
What year is the motor?
What ECU are you running?

 

92 B16A (JDM OBD1, not sure on the year), P30.


I know its the TDC(Crank angle) Sensor causing my car to go into limp mode..but whats random is that it isn't always on..sometimes it stops throwing the code while im driving.
