5. Repair Instructions:
Replace the knock sensor. Refer to
2.12.7.35 DTC P0335 P0336
1. DTC Descriptor:
DTC P0335
DTC P0336
CKP sensor signals ECM current crankshaft speed and position. CKP sensor produces an alternating voltage with different amplitude
and frequency. Frequency depends on the crankshaft speed, the output AC voltage depends on the CKP. The CKP sensor works
in conjunction with a 58X reluctor wheel that is attached to the crankshaft. ECM calculates the ignition timing, injection timing, and
knock ignition timing based on CKP sensor and camshaft position sensor input signals. CKP sensor is also used to detect misfire
and tachometer display. ECM uses CAN network to send the engine speed signal to the instrument cluster.
CKP sensor signal is sent through CKP sensor harness connector EO26 terminals A, B to ECM harness connector No.EO01
terminals No.21 and 20.

2.10.8.5 Knock Sensor Replacement.
Crankshaft Position Sensor Circuit No Signal
Crankshaft Position Sensor Circuit Signal Interference
Conditions For Setting The DTC
(Control Strategy)
1. During startup, the crankshaft
position sensor is disconnected,
short to Ground and short to
power supply.
2. Fault timer accumulated time is
longer than 2 s.
1. Crankshaft position sensor and
the signal tooth gap is too large.
2. The difference between actual
identified number of teeth and 58
teeth is bigger than a specified
value.
Intermittent Fault. Refer to
