Check Engine Light Codes

[PhinsJL]

2021 4XE has CEL codes p2225, p0121, p0415, c0063. I tried clearing with tazer but they all return. Any ideas on what to look into? Thanks.

All of those codes do not apply to your vehicle except the p0121. The c0063 is probably erroneous.

I would suggest trying a different scanner if those are the codes you are getting. The p0121 is a throttle body DTC and not common at all.

Thanks, I’ll try that. I’m reading them with tazer mini updated to the latest firmware.

How is your 12V battery? I know it sounds crazy, but low battery can cause all kids of weird happenings in our Jeeps. Being "new" doesn't mean anything nowadays.

If your '21 still has the factory battery then it might be time for a new one.
