•
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

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).
Level in wiring diagram: Temperature sensors
Location:
•
on the vehicle: on the front cylinder on
the internal side facing the rear cylinder
•
connector: on the sensor
