PFC and Sensor Question?
Was checking my sensors on my pfc and wanted to know if everything was the way it should be.

I tried my hardest to take a picture but it just wasn't working out thx to the sun. Let me know what you guys think, thx -Eric

According to the PFC manual, those sensors are for:
NTR: Neutral Switch
CAT: Catalyzer Thermo Sensor Switch
HWL: Exhaust Temp Warning Indicator
PAC: Port Air Control
CCN: Charge Control
That's what you'll see for having the clutch out, the gear select in N, the key in ON, and not having the engine running. From what I can tell, and it has nothing to do with your injectors. I'll have to check what my fuel voltage is, but that looks like it's reading a little high?

I think mine is on because the secondary fuel rail means there is no sensor attached, im not too sure fully because mine was like that when i brought the car, and the guy explained to me that it was not a problem. I am currently looking into getting it sorted because the heat light is on permantly on the dash and if something esle is failing on the car i am not going to know because the fault lamp is already lit

If a sensor voltage is always high (near 5v) and does not decrease with heat, then the wiring or sensor are bad, or sensor removed.
You may have, could have, can test this yourself if you think about it.

As for the fuel sensor:
I removed my fuel sensor, so my car always says 4.xx. Not a big deal. It is part of the hot-start system designed to compensate for hot fuel when starting up. Possibly also tweaks mixture when driving (???).
I have had mine removed for years, never missed it.

It won't affect day to day running but it will light the warning light on the dash of a Jap Import FD. Not normally a problem on US Spec cars because most of you guys haven't changed the wiring for the warning light to work.
