Program No.: A7

*EOBD: European On Board DiagnosticsSC007
RUN OBD TEST: O2 SENSOR
NOTESRepair all the electrical faults and clear them from the memory.
Program the flywheel target ET089 Programming the engine flywheel target.
It is preferable to run this command with a warm engine. This reduces the time it takes
for the catalytic converter to heat up.
The aim of this command is to detect a fault causing the EOBD* threshold for pollutant emissions to be exceeded.
There are two kinds of oxygen sensor damage:
– mechanical damage to the component (breakage, cut in wire) which leads to an electrical fault,
– chemical or thermal damage to the component leading to a slower response time of the sensor and to the
increase in the average reaction time.
Procedure:
– Engine stopped.
– Run command SC007.
– Start the vehicle without losing the + after ignition feed
– Wait for the command result.
Fault finding is entirely autonomous. When completed, the throttle control ceases and the engine returns to idling
speed regulation operation.
At the end of this test, four different results are possible:
–Status 1: Fault finding not carried out/impossible to obtain the necessary conditions.
–Status 2: Component in an average condition.
–Status 3: Component in good condition.
–Status 4: Component in poor condition.
When the command is complete and after the result has been read, stop the engine and start it again to obtain the
conditions relating to normal use.
If the result is Status 1: check for any faults, and the engine flywheel target programming using ET089.
If the result is Status 2 or Status 4: replace the sensor.
If the result is Status 3: the sensor is in good condition.

Never drive the vehicle without checking first that there are no throttle valve faults.
NOTESThere must be no present or stored faults.
