Condition for fault identification

Test condition:

The fault is recognized when the voltage of the charge-air temperature sensor does not change by at least 0.005 V.

Potential problem source(s):

• Defect in wiring harness between DME and charge-air temperature sensor
• Charge-air temperature sensor defective
• Charge-air temperature sensor has been tampered with
• Defective DME

Terminal condition: none

Voltage condition:

• Onboard electrical system voltage between 9 V and 16 V

Temperature condition:

• Engine warmed to normal temp, above 80 °C

Time condition:

• 27 sec. after reaching engine temperature of 80 °C

Other conditions:

Drive vehicle at a speed above 40 km/h for at least 2 minutes to reduce the charge-air temperature, then allow the engine to idle for at least 2 minutes to allow the charge-air temperature to rise again. This sequence must be repeated 3x.
