1A-140 Engine Control System (4JJ1)
DTC P0335 (Flash Code 15)
Circuit Description
The crankshaft position (CKP) sensor is located on the
left-hand of the cylinder block rear. The sensor rotor is
fixed on the crankshaft. There are 56 notches spaced
6° apart and a 30° section that is open span. This open
span portion allows for the detection of top dead center
(TDC). The CKP sensor is a magnetic resistance
element (MRE) type sensor, which generates a square
wave signal pulse. The sensor has the following
circuits.
• 5 volts reference circuit
• Low reference circuit
• CKP sensor signal circuit
The ECM monitors both CKP sensor and camshaft
position (CMP) sensor signal pulses to ensure they
correlate with each other. If the ECM receives a certain
amount of CMP sensor signal pulses without a CKP
sensor signal pulse, this DTC will set.
Condition for Running the DTC
• DTCs P0016, P0336, P0340 and P0341 are not
set.
• The ignition switch is ON.
• The CMP sensor signal pulse is detected.
Condition for Setting the DTC
• The ECM detects that the CKP sensor signal
pulses are not generated during engine rotations.
Action Taken When the DTC Sets
• The ECM illuminates the MIL when the diagnostic
runs and fails. Refer to DTC Type Definitions for
Action Taken When the DTC Sets - Type A.
Condition for Clearing the DTC
• Refer to DTC Type Definitions for Condition for
Clearing the MIL/ DTC - Type A.
Diagnostic Aids
• If an intermittent condition is suspected, refer to
Intermittent Conditions in this section.
• Electromagnetic interference in the CKP sensor
circuits may set this DTC.
• An intermittent CKP sensor signal pulse may set
this DTC.
• Ensure the sensor is tight and the sensor rotor
teeth are not damaged.
Notice: If the CKP sensor signal pulse is lost while
running, the engine will stop.

1. Turn OFF the ignition.
2. Disconnect the crankshaft position (CKP)
sensor harness connector.
3. Connect a DMM between the 5 volts reference
circuit (pin 3 of E20) and a known good
ground.
4. Turn ON the ignition, with the engine OFF.
Is the DMM voltage more than the specified value?
4.5 volts
