Engine Temperature Sensor - APRILIA SL 750 SHIVER Service Station Manual

Electrical system
•
Check the pneumatic system between the pressure sensor and the socket to read pressure
on the throttle body; check that the intake manifold is in good conditions and the pressure
reading hole is clean: there is an evident defect in the intake and pressure reading systems.
Pressure too low at front cylinder manifold error P0217 - signal not valid.
•
A small difference between the estimated pressure and the measured pressure has been
detected: the measured pressure is below the estimated one (for example, smeared throttle
body).
Troubleshooting
•
Check the pneumatic system between the pressure sensor and the socket to read pressure
on the throttle body; check that the intake manifold is in good conditions and the pressure
reading hole is clean.
Pressure too low at rear cylinder manifold error P0218 - signal not valid.
Error cause
•
A small difference between the estimated pressure and the measured pressure has been
detected: the measured pressure is below the estimated one (for example, smeared throttle
body).

Engine temperature sensor

ENGINE TEMPERATURE SENSOR
Function
it tells the engine temperature to the control unit so
as to optimise its operation.
Operation / Operating principle
NTC type sensor (resistance sensor, inversely
variable with temperature).
