I need to replace the cam sensor on my 99 FRC. I searched here and some threads talk about needing to do a 'relearn' after the sensor swap using a Tech II scanner. Is this necessary after a simple sensor swap? Is there another way to do the relearn without a Tech II?

Anytime the powertrain control module (PCM) or the battery is disconnected, the PCM loses power, or the PCM is reprogrammed, the PCMs learned idle position is lost. The engine idle is unstable when the learned idle position is lost.

Perform the following procedure in order to return the learned idle to the correct position:

1. Automatic TransmissionTurn OFF the ignition.
2. Restore the PCM battery feed.
3. Turn OFF the A/C controls.
4. Set the parking brake and block the drive wheels.
5. Start the engine.
6. Ensure that the engine coolant temperature is more than 80°C (176°F).
7. Shift the transmission into Drive.
8. Allow the engine to idle for 5 minutes.
9. Shift the transmission into Park.
10. Allow the engine to idle for 5 minutes.
11. Turn OFF the engine for 30 seconds.

Thanks Mark. Seems easy enough. Looks like we're almost neighbors, I'm out in Treasure Island most weekends.
