Crankshaft Sensor
Description -
In order that the ECU can control the engine at all the position of the crankshaft
must be known so that the cylinder in compression and the timing of the next fuel
injection can be calculated. The CKP is an inductive pulse generator, which scans
protrusions on the flywheel. Two teeth are missing, and this gap is situated at 90°
before TDC.

Crank signal fault - missing tooth
DTC detection condition Probable cause
Background
• When the engine is running, the Crankshaft
Position sensor outputs a pulse signal.
• The ECU checks whether the pulse signal is in
put while the engine is cranking.
•
Normal Operating condition
• Engine is being cranked.
Malfunction
• Normal signal pattern has not been input for
cylinder identification from the crankshaft
position sensor signal for 4 sec.
• No synchronization between crankshaft
camshaft signal.
Reaction
• System lamp continuously on.
• Engine will not start.
• If engine is running this fault occurs, engine
will stop immediately.
• The error will be in active mode during
cranking only.

P 0335: Crankshaft sensor – No signal
Possible Causes : Open circuit of the positive or the negative cable
Corrective Action : Check for Open circuit between 2 15; 1 14
P 0336 : Crankshaft sensor signal error.
Possible cause : This error can only come if any teeth signal is missing or
Improper.
Corrective Action : Look for damage on toner wheel teeth damage
P0371: F_M_Aps_crank_early_fault_rec
Possible Cause : This error can only come when the teeth are too close. It is
not expected to happen in a running vehicle.
Corrective Action : If reported check if the flywheel and the toner ring changed
just prior to the failure. Take corrective actions accordingly.
P0372 : Crank signal fault - missing tooth
Possible Cause : This error can only come when the teeth is shifted or missing.
It is not expected to happen in a running vehicle.
Corrective Action : If reported check if the flywheel and the toner ring changed
just prior to the failure. Take corrective actions accordingly.

Corrective action : Check for pin back out at pin 34 of EMS ECU or the pin 1. Check
the 34-1 for open circuit or short to ground
Possible cause : If the Ground wire is having problem. If the vehicle is running then
the engine will go into limp home mode and then after igniation OFF the engine
can not be started.
Corrective action : Check for the pin back out at Pin 20 Pin 2
Check for open circuit in Pin 20 of EMS ECU to Pin 2 of cam phase sensor
Possible cause :
If the Reference voltage wire is having problem. If the engine is running it will go
into limp home mode ( 1300 RPM) . After igniation off the engine can not be
