Engine Controls - MIL ON/DTC's P0111 & P2183 Set
08-001
January 12, 2008
Applies To:
2007 MDX - ALL
MIL Comes On With DTCs P0111 and P2183
SYMPTOM
The MIL is on with DTC P0111 (intake air temperature [IAT] sensor circuit range/performance problem) and DIG P2183 (engine coolant temperature
[ECT] sensor [sensor 2] circuit range/performance problem).
PROBABLE CAUSE
When a vehicle is parked in direct sunlight, the underhood air temperature can rise faster than the engine coolant temperature. This could create a higher
than normal voltage difference between the IAT and ECT sensors, causing the PCM to store DTCs P0111 and P2183.
CORRECTIVE ACTION
Update the PGM-FI software with the HDS.
SOFTWARE INFORMATION
HDS Software Version:
2.012.013 (December 2007) or later.
Application Version V6.10.06 or later.

NOTE:
If you use an earlier HDS software version, the HDS may incorrectly indicate that the vehicle does not need an update when it actually does.
