help. code 07 boost sensor. Forum Members?
i have 86 na with s5 engine, did led code check and showed 07 code.
i tested boost sensor everything looks fine getiing 12v--ground----5v----and 2v to ecu. vac line isnt cloged. but im still getting same code. do i have to reset ecu to clear the code? should this code be fixxed asap, will it harm the performance or realibility, thank you.

if you have a s5 motor how can you be running a s4 ecu?
if i was your ecu i'd be confused too!!.....code 420!

and the codes clear on a S4 ECU everytime you turn the key off.
And what on the S5 motor are you running. A S4 ECU won't run a S5 engine, as the S5 engine uses an electrical MOP.
Now maybe you have a S5 block and or you have the MOP removed and a S4 harness (since the S5 harness won't plug into a S4 ECU)... but either way, you are not being clear enough for someone to help you.

I'd take a look at where the boost/pressure sensors vacuum nose is connected to the engines intake manifold. Describe just where it's attached.
S4 don't need resetting from my experience. I can pull the plug off a tps/boost sensor/air intake sensor and the code will appear. Put said plug back on an the code goes south.
