Hej alla C4 ägare
Har fått felkod 13.....Open oxygen sensor curcuit.
Vad innebär det och vad kan det vara som orsakar det?

Kanskje denne infoen kan hjelpe :

mvh Øystein


CODE 13
Trouble Code 13 indicates that the exhaust stream oxygen-content sensor (O2 sensor) is not responding as expected. When cold, the sensor is 'biased' by the ECM to about 450 millivolts. Before it warms to at least 600 deg F (315 deg C) it acts as an open circuit and when the ECM reads it, it reads the 450 mV bias. The ECM expects the sensor to warm in a short period of time and begin sending its own voltages. The general conditions for this code getting set are:
? engine running at least 2 minutes
? coolant temperature at least 50 deg C (122 deg F)
? O2 voltage not fluctuating (i.e steady between 350 and 550 mV)
? TPS signal above idle
? all above conditions met for 60 seconds

Typical causes may include:
1. Defective or degraded O2 sensor
2. Deposit-contaminated O2 sensor (running leaded fuel, RTV silicone deposits etc)
3. Corroded/defective O2 sensor connection
4. Defective sensor ground circuit
5. Defective connection at ECM
6. Defective ECM
NOTE: If codes 21 and/or 22 are also present cause '4' above should be checked first.

Tack Öystein för svaret
Har beställt ny "oxygen sensor" misstänker att den felar och ger fel signal när motor blir varm.
