October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
Diagnostics, oxygen sensor 1.: Notes
- If the sensor lead is short circuited to the preheating circuit, diagnostic trouble code P1133 will be generated.
- If the current in the oxygen sensor pre-heating circuit is too low, diagnostic trouble code P1135 will be generated.
- If the current in the oxygen sensor pre-heating circuit is too high, diagnostic trouble code P1136 will be generated.
- If the sensor lead is short circuited to ground, diagnostic trouble code P0131 will be generated.
- If the sensor lead is short circuited to B+, diagnostic trouble code P0132 will be generated.
- If the sensor reacts too slowly to changes in the fuel-air mixture or if its voltage transition is too far from lambda 1, diagnostic trouble code P0133 will be generated.
- If there is an open circuit on any of the leads for the sensor ground or sensor voltage, the control module will continuously read 0.45V and diagnostic trouble code P0134 will be generated.
