Airbag Code 45

[bud168]

Hey guys, thought you might be able to help me.. I got in my 92 stang to start it up the other day since it hasnt been started in a couple weeks and all of the sudden the air back light seems to be flashing 45, it flashes 4 times then 5 so Im assuming that is that code. I did some research on the web and found that means "Center front sensor not mounted to vehicle properly", I visually checked it over and it looks fine. I didnt find any resolution to this on the web or anyone mentioning any quick fix, so any help would be appreciated on this..

Thanks Kurt

Hopefully, this one is simple.

A code 45 is because the air bag monitor sees more than 2ohms between the sensor mount and ground. So, first things first.

• Disconnect the battery. You don't really "have to, but it's always a good idea when doing anything to the air bag system.
• Take the sensor off.
• Use a wire brush (the toothbrush metal type that you can get at Home Depot), and/or sandpaper to get rid of any rust and to make a good clean connection.
• Use some dielectric grease between the sensor mount and bracket. If you don't have any, no big deal. That's okay.
• Connect up the battery.
• Turn ignition on, look for codes.

If the code 45 is still present, then you either have:

• A bad Sensor (most likely)
• A bad ground to that support. That can happen with these old Fox bodies.
• A bad wire to the sensor. Least likely.

We can deal with any of those if that's the case. None are that bad. At they very worse, you'd need to run a new wire. So, no big deal.

Sounds good!

I don't get to check the forums all of the time. If I don't reply back in the forums, then for air bag help, send me a PM. Make sure you put "Airbag Code 45" in the title. In general, I don't read or respond to PMs. So, if I don't recognize a PM, I ignore it. I'm swamped with my consulting gigs. But, I try to make an exception for air bag stuff.

Good Luck!
