OBD1 Codes

[Mk3 SuPrA]

Can anyone tell me if these codes are correct and what I need to do to fix the problem? I got a code 32 Air flow meter or vaccume sensor signal fault ....51 AC signal on... any help will be appreciated thanks.

Use search! 51 is tps needs to be adjusted 32 is likely a bad afm or the plug is not secured in all the way

On a GTE code 32 is the HAC sensor. 51 can be the TPS, NSS, or AC. It's usually the TPS.

ooo ok cool and from what I've read the HAC sensor is behind the glovebox right?.. thanks

HAC sensor is behind the glovebox for pre-'89 models, it's integrated into the ECU for '89+ models.

yea mine is a pre-'89 but it was an NA so does that mean it doesn't have the HAC sensor since its not built into the harness? the harness is off a pre-'89 also and i read only the GTE had the HAC sensors soooo?
