I have a 94 f-150 with the airbag flashing a code 23 anyone know what this code is. Thanks

 

Chiltons says 23 is TP sensor out of self test range. I'm guessing that means Throttle Position sensor.

 

PINPOINT TEST DTC 23: REAR AIR BAG SENSOR AND BRACKET INPUT FEED/RETURN CIRCUIT OPEN

Battery voltage is provided at air bag diagnostic monitor Pin 15 (Circuit 611, W/O) at all times. However, voltage at Pin 15 can be as high as 25 volts (as provided by the backup power supply) when the ignition switch is in the ON position and the backup power supply in the air bag diagnostic monitor is charged up. Circuit 612 (P/O) is connected to Circuit 611 (W/O) inside the rear air bag sensor and bracket. Therefore, the voltage at Pin 23 (Circuit 612, P/O) should be the same as the voltage at Pin 15 at all times. The air bag diagnostic monitor compares the voltage available at Pins 15 and 23. If the voltage at Pin 15 is normal and the voltage at Pin 23 is low, the air bag diagnostic monitor will flash out Code 23 to indicate an open between these two circuits.


Possible Causes

Low voltage at Pin 23 can be caused by:

1. An open circuit in the wiring harness in either Circuit 611 (W/O) or 612 (P/O).

2. An open circuit inside the rear air bag sensor and bracket across the W/O and P/O wires.

Uh.....yea.....what he said.....this was obviously way over my head. Nice catch subford!

 

Did the picture explain it all? I'm also having a flashing airbag light seems to be a code 23. Would someone please, break down Subford's post,WAY over my head also.

Thank You for the schematic and quick reply. So my thoughts were "now i need to get into the steering wheel" , then I see in a "related thread" theres some question as to where its located. In a Bronco its located by the seat belt retractor. Same place in a 94 reg cab?
