Engine Temperature Sensor - APRILIA RSV4 Factory 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.
Pressure too low at front 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).
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.

Engine temperature sensor

Function
It tells the engine temperature to the control unit to
improve its performance and to calculate the en-
gine friction for a better estimation of the generated
torque.
Operation / operating principle
NTC type sensor (resistance sensor, inversely
variable with temperature).
