AD07.52-S-6000-08A | PEC fuel injection and ignition system test of electrical system O2 sensor |
| Scope of test | Measuring instrument/ | Operation/Requirement | Specified value | Possible cause/Remedy | ||
1.0 | Oxygen sensor Sensor voltage too high Sensor cold –//– Sensor signal implausible Oxygen sensor signal | | Engine: Idling Actual value 07 at operating temperature | Fluctuates between -200 mV and + 1000 mV | Display approx. 30 mV ( ): 1.1 Display > 1000 mV (-//-): 1.2 Value in order: Oxygen sensor | ||
1.1 | Cable | | Engine: Idling Actual value 07 at operating temperature Disconnect connector of oxygen sensor/control module | If the display does not change: Cables to control module If the display changes to > 1000 mV: Oxygen sensor | |||
1.2 | Cable |
3 | Connector of oxygen sensor/ control module |
4 | Engine: Idling Actual value 07 at operating temperature Connector of oxygen sensor/control module disconnected | If the display does not change: Cables to control module If the display changes to approx. 30 mV: Oxygen sensor | |
