Table 2, Trouble Codes

The following tables give the information sensor and the possible cause of the fault for each trouble code. At the same time, the conditions are given under which the trouble -code in question is set. To find out the defective circuit or defective part, the remedial measure can be read off from the F0:DATA LIST via the reference code.

Conditions for setting fault:

The fault is recognized by the control unit if

· over a period of time t > 2.5 s

· the oxygen sensor voltage is in the region 380 to 590 mV (lead interruption, oxygen sensor defective)

Conditions for storage of fault:

The fault is stored and the replacement value called up if the following conditions are fulfilled consecutively:

1.) Coolant temperature T > 70 °C/157 °F,

2.) Condition 1.) is fulfilled for 3 min,

3.) Load signal > 3.5 ms,

4.) After conditions 1.) to 3.) are fulfilled, waiting time of 5 s elapsed,

5.) Trouble code 73 or 74 not recognized,

Replacement value:

If trouble code 13 was recognized, the control unit takes 450 mV as replacement voltage (oxygen sensor regulation switched off).
