First I want thank everyone who posted solutions on this board that helped me do the work on my wife's car.
Last week I pulled the intake off my wife's 2002 to replace a bad oil pressure switch, relocated it, change the plugs, cleaned the throttle body and the MAF.
It also had a bunch of codes including the C1214, so after researching this forum I removed the ECBM and found it was serviced before and they did poor solder job. I desoldered and resoldered the connections.
The car now runs great, has normal oil pressure reading and there is no longer the ABS/Traction control service warning.
But I now have C1287 HC and C1288 HC codes.
I came back, cleared the codes and went for another ride and the Service Active Handling warning came back.
I pulled the codes before I shut the engine off and the two codes came back, C1287 HC and C1288 HC, but no C1214!!
Any help would be appreciated.
Here are pictures of my board before and after.

Thanks for the reply.
I have access to Snap On scanners, can they be used to check the sensor?
Someone reapired the EBCM before I got the car, as shown in the first picture, so I will check all the connectors in the plug.

The SWPS are still available for your 2002. Had to replace the one on my '04. The part # is 88965543 and they cost about $70.

Just bought one for my 04 just in case. Who knows with GM will stop making them.
