Coolant temperature sensor
The engine temperature sensor is brown, located on the
front of the cylinder head. It is an NTC thermistor. The ECM
receives electronic signals from this thermistor and uses
them to determine the coolant temperature. This
information is used by the ECM to optimize fueling at all
engine temperatures and to calculate hot and cold start
fueling requirements. The sensor resistance decreases as
the temperature increases.
1. Coolant temperature sensor
Air temperature sensor
The intake air temperature sensor is green. It is
mounted on the front area of the airbox (base). It is a NTC
thermistor. The ECM uses the information from this
sensor to calculate the fuel necessary for a given air
temperature (based on information from other sensors.
NOTE :
Components have been removed for this photo. Here
the airbox is lifted to reveal the sensor location.
