I am not positive but I think if there is any CEL on the then remote start won't work. As soon as the code is cleared the remote start should work again. This is how it worked when I had a CEL for a bad valve cover.

Laundry list of codes. Cleared with snap on box.
P0121
P0420
P1101
P2227
P2261
U0121
B125C
U0121
One other thing my remote start stopped working. I hit the button the car makes a light flash saying it got the order but does not start.

When watching the Applied petal percentage, and throttle position sensor they are not in proportion. When applying signal to petal the throttle opens 100%.
- Is there something for accelerator learning.

Was told I may have a bad TPS ??? Don’t see how it could be bad. I removed throttle body and re installed it. TPS is on the side of throttle body correct ?

Ok. Things getting better , getting worse???

So some different codes today some the same.

And YES ! CEL will cause auto start to be disabled!!! Was I glad it worked after clearing today’s codes.

Codes that are reoccurring :
P0121 TPS - This is a mysterious one ???
PO420 Catalyst -Aftermarket down pipe
P2261 Bypass valve stuck -Bypassed the bypass

-Today I had Intake air codes.

P0097 ITA Sensor 2 L.V. Fail
P00F4 IAT Humidity L.V. Fail
P0113 IAT H.V. Fail
P1101 Intake Air Performance
P2227 BARO Sensor performance
P2228 BARO L.V. Fail

In addition to the three reoccurring codes.

These codes were appearing when i would have a boost spike , I tightened up the band clamp at the MAF. That may have contributed to all the problems and codes.
