I just finished replacing the thermostat and carbon cleaning the intake valves, and now my 2009 Clubman S will crank, but not fire. Clearly there are a lot of connectors and vacuum lines that I had to disconnect and reconnect for this process, and even though I numbered the connectors as I went, I suspect I've got something hooked up incorrectly. I can smell fuel, so I don't think I have a problem with the pumps, I think instead I'm looking at a problem in the ignition system.

I hooked up my diagnostic software, and got two error codes:
1) 289D: O2 sensor or boost pressure sensor
2) 2EF2: Intake air temp sensor

I can't find pics of these sensors in Bentley to check, can anyone tell me where to look or have pics?
Thanks in advance for any help!

 

You shouldn't have had to remove either of those sensors to do either of the jobs, but the IAT sensor is on the charge piping on the passenger side of the engine bay, right up top, and the O2 sensor you're looking for is in the lower section of the downpipe, which you shouldn't have had to touch. If you're getting a boost related code along with the IAT code I would look more into the sensor on the upper charge piping.
