Page: 201 / 285

FAULT CODE
199
Flash code FI warning
lamp (MIL)
02 FI warning lamp ( MIL ) flashes 2x short
Display on diagnostic tool P0335
"Circuit ignition pulse generator"
"Malfunction in the circuit"
Error level condition
The manifold absolute pressure sensor is generating a standard signal (the engine is running),
whereas the ignition pulse generator is not generating any signal.
The engine will be switched off:
≥
1 s
Function check Ignition pulse generator - checking the signal ( p. 199)
Possible cause
Ignition pulse generator - value not plausible ( p. 199)
Ignition pulse generator - signal lines are open ( p. 200)
Ignition pulse generator - signal lines have a short circuit to each other ( p. 200)
Ignition pulse generator - signal lines have a short circuit to ground (terminal 31) ( p. 200)
Ignition pulse generator - signal lines have a short circuit to sensor ground ( p. 201)
Ignition pulse generator - signal lines have a short circuit to plus (terminal 30) ( p. 201)
Ignition pulse generator - signal lines have a short circuit to ignition plus (terminal 15)
( p. 202)
Ignition pulse generator - signal line has a short circuit to the sensor power supply ( p. 202)
