EmissionsRelevant

Drive cycleRequired

Limp modeNo

After a long standstill (six hours in a documented case) all intake air temperature sensors, for example intake air, charge air cooler and manifold temperature, should read about the same. The control module compares them in pairs: if one sensor stands out, it sets that sensor's own plausibility code. This code is set when no pair agrees, so no single sensor can be identified as faulty. A detected engine preheater suspends the test. Since it runs only after a long standstill, the code may take a night to return after being cleared. Some vehicles also disable start-stop while this code is stored.

Likely causes

One temperature sensor drifting without setting its own code

Uneven cooling, undetected preheater or strong sunshine

Shared ground or reference line disturbed, falsifying several sensors

Engine control module or software

Symptoms

Check engine light on
Start-stop disabled on some vehicles
Usually no drivability symptoms
