My list does not show that code. Are you sure that'* correct? It should be a P code and they start at 101 with the exception of 2000-2001 engine codes which have 2 codes under P0101.

The only thing I could find for a P0100 is a generic Mass or Volume Air Flow Circuit Malfunction.

Are you using an ODBII reader or a Tech II diagnostic tool?

Also, please add your year and trim of your vehicle to your signature line. That way when you start asking questions in other areas of the forum, we all have a better idea on how to assist you. Click on "Quick Links" above, go down to "User Control Panel" and then click on "Edit your Signature" It'* pretty straight forward from there.

The following applies to how codes are assigned:

P #### - Powertrain
B #### - Body
C #### - Chassis
U #### - Data communications

DTC B0100, B0101 or B0102 Electronic Front End Sensor 1 Performance

The following conditions must be met in order to set the DTC B0100:

- A valid ID message is not received within 5 seconds of the EFS (Electronic Frontal Sensor) being powered up.
- Status message is not received.
- The SDM (Sensing & Diagnostic Module) has reset the EFS twice without detecting a valid ID message.

The SDM commands ON the AIR BAG warning lamp via a Class 2 serial data message.

The following conditions may cause the malfunction:

- A short to ground or voltage in the EFS circuit.
- High or low resistance in the EFS circuit.
- Improper EFS installed on the vehicle.

One possibility is that there is corrosion in the connector where the EFS plugs into the body harness. It is also quite possible that you have a bad EFS. The other possibility is a bad SDM, however I suspect this is less likely.

If you're not familiar with servicing the Supplemental Inflatable Restraint system, I'd recommend taking it to a shop. This isn't really a system you'd like to service incorrectly.

Code is for the inflatable restraint electronic frontal sensor located at the body front end.
