Where is the ambient air temp sensor in the Pete?
In the Pete the Ambient air temp sensor is located in the drivers side mirror, It is a pain to replace. The ambient air temperature sensor is a variable resistor sensor and is used to measure the temperature of the ambient air.
What is the fault code for ambient air temp?
Fault Code: 249PID: P171SPN: 171FMI: 3/3LAMP: AmberSRT: Ambient Air Temperature Sensor 1 Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage detected at ambient air temperature circuit.
Where is the IAT sensor on an air cleaner?
The IAT sensor is usually located in the air intake boot, but it may also be located in the air cleaner housing or intake manifold. Step 2: Disconnect the negative battery cable. Disconnect the negative battery cable and set it aside. Step 3: Remove the sensor’s electrical connector.
What does FMI stand for in truck diagnostics?
FMI” is the Failure Mode Indicator. This number represents the type of failure detected. Refer to Failure Mode Indicators (FMI) below for more information. Active” or “Previously Active” will be displayed to identify whether a fault is currently active or if the fault was previously active. OC” is the Occurrence Count.
What does SPN stand for on a body controller?
DEFINITIONS •“SPN” represents the Suspect Parameter Number. This number identifies the item for which diagnostics are being reported. •“FMI” is the Failure Mode Indicator. This number represents the type of failure detected. Refer to Failure Mode Indicators (FMI) below for more information. 2 BODY CONTROLLER DIAGNOSTIC TROUBLE CODES (S08327)

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.
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.
