P0130 Lambda 1 signal above catalyser error

Unread post by BartW »

Ik heb een terugkerende error (1x gewist met FiatECUScan) zonder dat het motor management lampje aangaat.

Weet iemand wat de oorzaak kan zijn.
Mijn diva heeft nu 135k gelopen.

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.

Om te beginnen alle connectors goed schoonmaken (ook van de ecu's op het blok), en de uitlaat van begin tot na de lambda op (kleine) lekkages controleren.
Bij mijn 3.0 kwamen de vreemdste meldingen toen de massakabel tussen transmissie en chassis half gaar was.

Hi Hans, ok ik ga eerst de massakabel vervangen die ziet er erg groen uit
bedankt

Die kabel kun je ook tijdelijk overbruggen met een startkabel om een goede massaverbinding te maken zodat je kunt testen of dat het probleem is.

Hi Hans
ik heb de massa kabel vervangen, die zag er erg slecht uit. De auto start wel beter nu.
de stekkers van de computer heb ik nog niet gecontroleerd, ook aan de onderzijde heb ik nog niks gecontroleerd

ik heb een 2e foutmelding erbij sinds vandaag, deze ook maar gewist. eens kijken of deze terug
P1135 Preheating resistance 1 above catalyser

ERROR DETAILS:
Engine temperature: 85,5 °C
Engine speed: 2080 rpm
Engine load: 36,75 %
Air temperature: 28,5 °C
Throttle angle: 10,98 deg.
Battery voltage: 13,809 V

The Lambda sensor heater circuit indicated by the code is faulty. Possibly an open or a short to the ground.
Since the sensor is heated by the exhaust gases only, the sensor reaches the operating temperature slightly slower than normal, and may cool down too much during cold idle conditions to provide a valid signal for the fuel system closed loop operation.
Check the Lambda sensor heater circuit and relay/driver circuit for opens, shorts and weak connections, and ensure the proper voltage supply.
The reason for this fault is that ECU has received invalid 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.

Probleem opgelost, het waren de stekkers onder de auto naast de uitlaat bij het achterste spruitstuk.
