Hi all,
I'm new to the forum so let's see how this works out. I have a 2008 CX9 and I've had to replace the throttle body 5 times from January '22 to today (March 17, 2022). Each and every time I get codes P2101, P2104, P2110, P2111 and P2112, which from what I can tell are all TB related. The TBs don't go to catastrophic failure immediately. It might fail once one week and recover after a few minutes, then two or three times the next week, then every morning until it doesn't recover at all. I then replace with a remanufactured one from Cardone. I have never tried new, since they have no warranty here being electrical, and are very expensive from the dealership. When they start failing I can either turn the engine off wait a while and it's gone if that doesn't work I will leave it idling for a long while and it slowly goes away. This works most of the time until it just doesn't recover anymore. Codes are very difficult to clear having to repeat the clear several times. Disconnecting the battery will only clear codes occasionally. It will always have both the check engine light and wrench light on. My thoughts are that either the Cardone remans are not that well repaired (I get them from Rock Auto) or the ECM (engine control management) is bad and damaging the TB. I've checked the wiring and connector plugs. Another interesting thing is that twice, after turning the engine off during separate occasions, the A/C will turn on and only turn off if I turn the switch to start without starting or pull the neg cable from the battery... weird. After replacing the TB the CX9 will work ok for a few weeks maybe a little over a month and start failing again. Since the codes are very specific to the TB I haven't tried any other thing. Any ideas or help is good and worth trying. Big thanks in advance!!!
