I changed my plugs and cleaned my throttle body intake (TBI) and when I plugged everything back in and connected the negative on my battery. the check engine light came on and I started getting error codes on my reader. I cleared them and they just keep coming back. Everything I could find online said that they were related to the computer compensating for a dirty intake and then when it is cleaned it doesn't recognize the new position.

How do I or can I clear these codes? My H3 is running smooth with the new plugs but it feels like it has lost power due to the TBI issue.

They should clear out after a few cycles. May take a week or so to relearn.

Hello, I got the same situation.
After cleaning the MAF and TB with their corresponding cleaners and putting all back together. P1516 appeared.
What I noticed was that power locks and alarm does not work, after connecting battery.
Vehicle starts to 2000rpm than drops to ~1400 for ~`25 secs, suddently drops to 100 and then 500 and starts hesitating (abruptly cycling ) with REDUCED POWER TRACTION FAILED message. Anyone has an idea what to do? thanks.
Noticed while cleaned TB the blade was kind of stuck and cleaned it without moving it (closed).
the only things that realized was:
1. Disconnect TPS harness with Battery ON ( later disconnect)
2. intake-PCV hose was a little cracked but seemingly functional
3. During Vacuum hose removal broke one of the plastic ends of the lock.


Please share your thoughts.
Thanks .
