Heater core blew followed by a chewed up drivers side inner and outer bearings. I replaced the bearings and heater core but after attaching up the battery, the airbag light flashes. Yes, I did connect the harness back up. Any hints? <img src="/forums/images/graemlins/scared.gif" alt="" /> I also have a P0440 CEL code and have changed the gas cap. I will be cleaning the throttle body next weekend as well as changing the PCV valve. I did notice that after cleaning the present PCV valve I temporarily get less blow back ( intermittent/plugged pcv ) Any thoughts?

You must have disconnected an airbag before the electrical system was totally discharged or before the battery was disconnected. In order to prevent the airbag diagnostic unit from setting a check light the following must be done before disconnecting any airbag wiring:

1. Disconnect the battery.

2. Turn on the headlights.

3. Wait approx 15 minutes.

If this procedure wasn't followed the airbag system will indicate a fault. The only way to reset the system is with a Kia Pro Scan Tool. And only Kia Dealers have this tool so unfortunately you must visit a dealer and have the system reset. And expect to be charged a diagnostic fee.

If a new gas cap didn't fix the P0440 code then inspect all the vacuum lines going to the vapor canister unit.

Replaced the PCV valve and cleaned the throttle body. I did find one hose to the vapor canister that wasn't on tight. Is the vapor can. supposed to sound like sand, and is there a purge filter that should be replaced on it?
