2002 Camaro Z28 (5.7L LS1)
Please help restore my sanity. For six months I have been trying to get the obd2 internal monitor to run the catalytic converter test. I live in the Peoples’ Republic of California, so it’s important.
What I have done…
I have done countless “drive cycles”
Replaced input air temp sensor
Replaced air filter
Cleaned MAF sensor
Replaced all four O2 sensors
(I only have about 75 miles on it since I replaced the O2’s)
DOES ANYONE KNOW what exactly has to go right in order for the computer to run the tests? I would dearly love to see a flow chart.
Help, please, help!
