STOREDDOWNSTREAM OXYGEN SENSOR CIRCUIT
CO: Open circuit
CC.0: Short circuit to earth
CC.1: Short-circuit to + 12 V
1.DEF: Non-compliance with emission control standards
NOTESPriority when dealing with a number of faults:
If faults DF011 Sensor feed voltage no. 1,
DF046 Battery voltage,
DF601 Upstream oxygen sensor heating power circuit,
DF084 Actuator relay control circuit,
are present or stored, deal with these first.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after:
– a road test driving smoothly after the fan unit has been running, and ET056 Double
richness loop is ACTIVE,
– a smooth driving road test after the fan assembly has been in operation, immediately
followed by a road test on a slope at no load (injection cut-off in the deceleration
phase).
Special note:
–OBD warning light illuminated.
Check the cleanliness and condition of the downstream oxygen sensor connections.
Repair if necessary.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Use the "Universal bornier" to check the insulation and continuity of the following connections:
Computer, connector C, track B2 track D of the downstream oxygen sensor
Computer, connector C, track A2 track C of the downstream oxygen sensor
Repair if necessary.
If the fault is still present, deal with the other faults then proceed with the conformity check.
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.

NOTESPriority when dealing with a number of faults:
Deal with fault DF011 Sensor supply voltage no. 1 first if it is present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after the accelerator pedal changes from no load to full
load.
Special note:
–level 1 or 2 fault warning light lit,
– defect mode types 3 and 4: regulation of pedal's engine or vehicle speed setpoint,
speed limiter at 54mph (90 km/h) and loss of power during acceleration (pedal feels
soft).
Check that the pedal mechanism has not seized.
Check the cleanliness and condition of the pedal potentiometer connections.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Repair if necessary.
Use the "Universal bornier" to check the insulation and continuity of the following connections:
Injection computer, connectorA, track F4 track 6 of the pedal potentiometer gang 2
Injection computer, connectorA, track F2 track 2 of the pedal potentiometer gang 2
Injection computer, connectorA, track F3 track 1 of the pedal potentiometer gang 2
Repair if necessary.
Measure the pedal sensor resistance gang 2 between tracks 6 and 1.
Replace the accelerator potentiometer if the resistance is not 2.8 kΩ±2.05kΩ.
If necessary replace the sensor.
If the fault is still present, contact the Techline.
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.
