Yes

Mechanic's Assistant: Are you fixing your SRX yourself? What have you tried so far?

Yes and all of the above

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Checked fuses that I thought applied to the issue

Getting tired of throwing money at this, lol. Started out with P0300, 0302,0305. Last time before I reset the codes and changed the cam sensors, was P0420
Customer reply replied 4 months ago
No phone call
Cadillac Mechanic: ggrote1, ASE Certified Technician replied 4 months ago

so if you clear the codes what is the code that resets the 420 ?

Ask Your Own Cadillac Question
Customer reply replied 4 months ago
Haven't had any of the other codes, just the 420 now
Cadillac Mechanic: ggrote1, ASE Certified Technician replied 4 months ago

the 420 code is a cat converter code usually will set when the converter is damaged from a misfire issue

the odds are the 420 was set and has damaged the cat from when the engine was misfiring when acting up and caused this issue

if you clear the code and the 420 comes back i am sorry it will need a new cat convertor

if you have any questions please ask
