Notes:

  • ◆ The fault tables are listed according to the 5 digit fault code on the left.
  • ◆ Explanation of the fault types (e.g. "open circuit/short circuit to earth"):

=> Fault reader operating instructions

  • ◆ If components are indicated as faulty:
    First check the wiring and connectors to these components as well as the system earth connections according to current flow diagram. This is particularly relevant if faults are output as "occurring sporadically" (SP).

- Check speed signal

Wiring open circuit

- Locate and eliminate wiring open circuit using current flow diagram:
=> Current flow diagrams, Electrical fault finding and Fitting locations binder

No signal

Speedometer does not indicate vehicle speed:

Speedometer sender (G22) defective

- Replace G22

- Continue fault finding according to fault finding programme for MFI:
=> Current flow diagrams, Electrical fault finding and Fitting locations binder

1)     Checking the road speed signal is carried out when driving the vehicle at an engine speed between 2500 and 3000 rpm.

00513

Engine speed sender -G28

No signal

Wiring open circuit

- Check G28 => Page 24-57

G28 defective

- Replace G28 => Page 24-9 , item 14

Implausible signal1)

Gap sender/sender wheel too large

- Check G28 is seated securely/metal particles => Page 24-9 , item 14

Metal particles on G28 or holder loose

Sender wheel defective, loose

- Check sender wheel is seated securely:
=> Repair group 13; Removing and installing crankshaft

1)     In isolated cases, fault may be stored as a result of engine being abruptly stalled (sporadic fault).

Note on fault code 00513:

If due to a defect the engine does not run: Before interrogating the fault memory operate the starter for at least 5 seconds and then do not switch the ignition off . Because there is no signal from the engine speed sender when the engine is not running, the self diagnosis could mistakenly recognise an engine speed sender -G28 fault. If the fault remains stored in the fault memory, check the sender as described.
