2006 SANTE PCM ZR6 check engine light

[Mlagrone]

I think I had some bad gas. Had a "knock sensor see dealer" code. I was able to clear the code with a code reader. But the check engine light is still lit.I have good oil pressure, good temp, good volts...ran it it my driveway for 10 min, any ideas?

no advise?

What was the code number?

I cleared the codes and the CEL is still on. The "knock sensor see dealer " message is gone.

Could be the temp sensors on the exhaust manifold riser/elbow going bad if this is happening and your operating temps are normal. Try unplugging them and see if that makes the light go away. I know PCM eventually eliminated them on the zR6 and other members have unplugged/ taped off the leads when their sensors go bad as well.

And certainly it's money well spent if you're not up-to-date, change that silver fuel filter on the left-hand side. Also I add stab-il 360 to my fuel as it measures. I think it's 1 ounce per 10 gallons for valve life.

But I figure all the fuel system upkeep is cheap insurance either way. Certainly not a bad idea if you're still chasing potential problems

What code reader did you use to check/reset the code?

please tell me the location of these sensors. are they on the intake someware or as you say on the exhaust pipe?

On top of the exhaust manifold riser.

Did you disable power from the batteries after resetting the codes? Did you use codemate to clear them?
