•
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 a very evident defect in the intake and pressure reading sys-
tem.
Front bank intake manifold pressure estimate error P1603
•
pressure too high/pressure too low.
Error cause
•
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 a very evident defect in the intake and pressure reading sys-
tem.
Rear bank manifold pressure too low error P1604
•
signal not plausible.
Error cause
•
Small difference detected between the estimated pressure and the measured pressure: 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.
Front bank manifold pressure too low error P1605
•
signal not plausible.
Error cause

Small difference detected between the estimated pressure and the measured pressure: the
measured pressure is below the estimated one (for example, smeared throttle body).
