UPSTREAM O2 SENSOR
NOTESThere must be no present or stored faults.
Check the cleanliness and condition of the upstream oxygen sensor and its connections.
Repair if necessary.
With the ignition on, check for + 12 V on track A of the upstream oxygen sensor connector.
If +12V is not present:
– disconnect the battery,
– disconnect the connector marked PPM1 from the Protection and Switching Unit,
– check the cleanliness and condition of the connections,
– using the Universal bornier, check the continuity on the following connection:
Protection and Switching Unit track 2 connector PPM1 track A of the upstream oxygen sensor
Reconnect the Protection and Switching Unit connector and reconnect the battery.
With the ignition on, if there is still no +12V at the upstream oxygen sensor connector, there is a fault in the
Protection and Switching Unit.
Contact the Techline.
Disconnect the battery and the injection computer.

Flywheel signal programming reinitialisation procedure:
Accelerate up to 4000 rpm in third gear ratio, then decelerate to power take-up speed*.
Then repeat immediately.
(* This is the moment when, during deceleration with no load, the engine drops to idle speed and recovers torque.)
If the fault is still present, check the cleanliness and condition of the flywheel.
