Diagnostic Aids
• This fault will set when inlet air is hotter than normal. The most common cause of high inlet air temperature is a
result of a problem with routing of the inlet air. Ensure inlet plumbing sources are external, is cool, and is not too
close to the exhaust at any point.
• Inspect the inlet air system for cracks or breaks that may allow unwanted underhood air to enter the engine.
• If no problem is found, replace the IAT sensor with a known good part and retest.
