Description
Camshaft speed sensor: the ECU receives no
signal and uses the signal from camshaft
speed sensor as alternative to calculate the
engine speed
Threshold:
ECU measures a deviation between cam-
shaft and crankshaft angle to target.
Sensor crankshaft speed; disturbed signal
Crankshaft speed sensor: the ECU receives no
signal and uses the signal from camshaft
speed sensor as alternative to calculate the
engine speed.
Fuel filter water level sensor: the voltage of
sensor measured by ECU is out of the target
range
Fuel filter water level sensor: the voltage of
sensor measured by ECU is out of the target
range.
Low fuel pressure sensor: the voltage of sen-
sor measured by ECU is out of the target
range
Low fuel pressure sensor: the voltage of sen-
sor measured by ECU is out of the target
range
Low fuel pressure: the low fuel pressure cal-
culated by ECU is underneath the target
range; the ECU activates a system reaction
Cold start aid relay error.
Cold start aid relay open load
Possible Cause
Error in sensor or wiring.
Offset error between crankshaft and camshaft. Threshold for error detection is an internal ECU
Error in sensor or wiring.
Crankshaft sensor defect.
Error in sensor or wiring.
Sensor not connected or sensor defect.
cable break or short circuit, sensor defective,
connection cable damaged.
Short cut to ground.
cable break or short circuit, sensor defective,
connection cable damaged
Short cut to battery or open loop
cable break or short circuit, sensor defective,
connection cable damaged
short cut to ground
Fuel pressure below warning threshold
Relay defect or wire harness problem
Relay or wire harness
Action
Threshold for error detection is an internal ECU
threshold, occurs by disturbed or no
camshaft signal.
Check increment wheel position, clean and
adjust if necessary, check sensor postition.
Check Camshaft Sensor or wiring.

not working, check sensor and if
necessary replace it,
check connection cable and if necessary repair
or replace it.
Check sensor and if necessary replace it, check
connection cable
and if necessary repair or replace it.
