Code 7 and code 22 check engine - Honda Prelude Forum

preludeh2394 · 09-11-2010, 08:20 PM

Ok so after I swap out h23 to h22 my check engine light is on. And it's throwing code 22 which is the vtec pressure valve/switch and idk how to fix it cause I put it in righ and I wired it right too.
Mine is h23 so it's prewire for vtec so I plug in the sensor and I ground a wire but it still throwing the code.
As for code 7 it says throttle angle and I have no idea on how to fix that or what it's going there.
Let me out please.
Thanks.

There's 2 sensors on the spool valve for VTEC, one is the VTEC solenoid and the other is the oil pressure switch, the only one that the car comes pre-wired for is the solenoid which is a single green/yellow wire. Code 22 is the oil pressure switch, you sure you got it hooked up right? Take some pics to show how you have it and maybe we can go from there. As for code 7, that sensor is more commonly known as the TPS or throttle position sensor, you could take this off your H23a1 throttle body, it's on the backside but you'll need to calibrate it.
