Ground locations

Post by widtrak77 »

On my 99 SSEI can anyone tell me where G101 and G106 grounds are located?
I have the service manual but I can't find in there where these are.
I have a C1277 code and the first diagnostic step is to check these grounds.
Any help much appreciated. Happy Holidays to everyone.

G101 is on the rear of the engine block near the oil pressure switch. G106 is in the left front of the engine compartment near the air cleaner.
