P0130 Lambda 1 signal above catalyser error
Posted: 25 Mar 2020, 20:32
Ik heb een terugkerende error (1x gewist met FiatECUScan) zonder dat het motor management lampje aangaat.
Weet iemand wat de oorzaak kan zijn.

P0130 Lambda 1 signal above catalyser error
ERROR DETAILS:
Engine temperature: 93,0 °C
Engine speed: 1920 rpm
Engine load: 22,50 %
Air temperature: 33,8 °C
Throttle angle: 6,67 deg.
Battery voltage: 13,882 V
The oxygen sensor signal indicated by the code is incorrect, out of range or missing. This Lambda sensor monitors the residual Oxygen in the exhaust, after the HC, CO and NOx eliminating reactions, and enables the ECU verify both the converter and the pre-cat. Lambda sensor functions. Depending on system, the sensors may be of the 0-5V or 0-1V type.
Usually, if the system is in good working order there is a small quantity of oxygen in the exhaust and the signal rarely reacts. Mostly, a signal reaction can be seen by e.g. snapping the accelerator quickly several times (strong enrichment).
Before replacing the sensor, check:
- Check the post-cat. Lambda sensor signal behavior from the data parameters or with a Multimeter or Oscilloscope: enrich strongly the mixture with repeated throttle snaps
- the exhaust for excessive O2 with an exhaust analyzer
- the exhaust system for leaks between and near the lambda sensors and at the converter to exhaust joints
- Aux. Air system (if present) for leaks or excessive air supply.
The reason for this fault is that ECU did not receive signal from the sensor. The fault is not detected now, but it is stored in memory. Clear fault codes, and observe for future appearance of the same fault. Dashboard warning light was activated for this fault.
