I have Acura RDX 2007 and the AC does not work. I took it to dealership/mechanics and they saw that the outside air temp sensor somehow banged condenser and had to replace the condenser. The diagnostic tool says B1227, I checked the outside air temperature sensor with a multimeter and it looks good. Could it be the connector? how to test them.
I tried self-diagnostics (holding "Off" key and clicking defogger key 5 times) but it does not show any error (it was supposed to show "C and Auto" for the same DTC shown in Diagnostic tool. )
Everything else was checked out by dealership mechanic and now it has become too expensive for the worth of the car. I am thinking it could be wiring or connectors, can anyone help with how does the signal flow and to where? like does outside temp air sensor signals the climate control unit first or can it be bypassed?
Command from HDS engages the AC clutch and it works, so the circuitry looks good (still not sure about the harness that goes from outside temp sensor to climate control unit)
