(PIN 3): if NOT OK, restore the wiring harness; if OK, check the continuity of the Green/
Black cable (between PIN 3 of the sensor connector and ENGINE PIN 32) and restore the
wiring harness.
•
If open circuit, short circuit to negative: check the continuity from the probe connector (PIN
3 and 4) to the probe: if NOT OK, replace the probe; if ok, perform the check procedure for
the sensor connector and for the Marelli control unit connector: if NOT OK restore; if OK,
with the key ON and the sensor connector disconnected, check if there is battery voltage at
PIN 4: if NOT OK, check the continuity of the Red/Brown cable between the probe connector
and the injection relay (no. 17 in the electrical circuit diagram, position under the left side of
the tank; however, CHECK the relay identification with the cable colours); if there are also
errors regarding the coils, injectors and secondary air, check the relay and its energy and
power line; if there is voltage at PIN 4, check ground insulation of the Green/Black cable
(PIN 3): if NOT OK, restore the wiring harness; if OK, check the continuity of the Green/
Black cable (between PIN 3 of the sensor connector and ENGINE PIN 32) and restore the
wiring harness.
WARNING
The control unit does not detect the following malfunctions of the lambda probe circuit relative
to the signal: interrupted circuit, short circuit to ground or malfunction of the sensor (for ex-
ample, voltage not variable). If the indication is abnormal, perform the troubleshooting indicated
below.
Troubleshooting
•
Check the continuity of the circuit from the probe connector (PIN 1 and PIN 2) towards the
probe: replace the lambda probe if there is no continuity; if there is continuity, check the
sensor connector and the Marelli control unit connector: if NOT OK, restore; if OK, check
the continuity between the ENGINE connector PIN 10 and PIN 22 and restore the wiring
harness.
DIAGNOSTIC TOOL: LOGIC ERRORS
P0134 Front lambda probe
Functional diagnosis:
•
no switching from high / no switching from low
Error cause:
•
If no switching from high: is shown when the ratio control is in closed loop and when the
secondary air valve is not operating. The error is validated if the engine is in CUTOFF status
and the probe signal is close to 1V, or if the engine is in another operating condition that
requires the injection but the switching from the"HIGH RATIO" to "LOW RATIO" is missing
for a certain"adjusted" number of dead points (PMS or TDC).
•
If no switching from low: is shown when the ratio control is in closed loop and when the
secondary air valve is not operating. The error is validated if during the ratio control stage,
