Why is my SPN 171 fault code 249?
Why is my SPN 171 fault code 249?
REASON: Ambient Air Temperature Sensor 1 Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage detected at ambient air temperature circuit. EFFECT: None on performance.
What causes a fault code to be active?
If necessary, recalibrate the ECM. The ambient air temperature sensor shares return wires in the engine harness with other sensors. Opens and shorts in the engine harness can cause multiple fault codes to be active. Check active fault codes with multiple counts first.

When to use amber check engine light ECM?
The ECM detects that the ambient air temperature signal voltage is greater than 5.13-VDC for more than 1 second. • The ECM illuminates the amber CHECK ENGINE light immediately when the diagnostic runs and fails. • A default value for the ambient air temperature reading is used.
Where is the ambient air temperature sensor located?
The ECM monitors the change in voltage caused by changes in the resistance of the sensor to determine the ambient air temperature. The ambient air temperature sensor is located in the air intake. This diagnostic runs continuously when the keyswitch is in the ON position.
What are the fault codes for Cummins engines?
Cummins engines fault codes list Error code 111 Engine: ISF 2.8, ISF 3.8, ISB, QSB, QSC, ISL, QSL, ISM, QSM, ISX, QSX Error: ECM internal failure. Description: This DTC can only occur if there is a problem inside the ECM.
What is fault code 2398 for ambient air temperature sensor?
Today fault code 2398 popped up for ambient air temperature data erratic. can anyone help me located this sensor. The ambient temp sensor is inline with the drivers side mirror harness. They will try and sell you the complete mirror for $1200. but you can just buy the harness for about $200.
