Intake Air Temp Sensor Testing

• Check status on DISplus status pages (0-5 volts). Ensure that voltage changes and does not remain constant at 0 or 5 volts.
• Check Sensor Resistance
• Perform TEST PLAN

Workshop Hint MAP and TMAP Sensors 

• Voltage Reading of approx. 1-2 volts indicates high vacuum condition (Idle or no load)
• Voltage Reading of 4-4.8 volts indicates low vacuum condition (Full Throttle)

Workshop Hint Air Inlet Temp Sensor 

• Workshop Hint MAP and TMAP Sensors Voltage Reading of 1 volt indicates warm air temperature
• Voltage Reading of 4 volts indicates cold air temperature
