Electrical system
•
A substantial difference between the estimated pressure and the measured pressure has
been detected (for example, the pipe between sensor and throttle body is fully detached/
clogged or squashed).
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: there is an evident defect in the intake and pressure reading systems.
Pressure too low at rear cylinder manifold error P0217
•
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.
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.
