INSPECTION PROCEDURE
HINT:
Read freeze frame data using the hand−held tester . Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was
running or stopped, if the engine was warmed up or not, if the air −fuel ratio was lean or rich, and other data
from the time the malfunction occurred.
1 INSPECT CAMSHAFT POSITION SENSOR(RESISTANCE)
(a) Disconnect the C 1camshaft position sensor connector.
(b) Measure the resistance between the terminals of the camshaft position sensor.
Standard:

NOTICE:
The terms ”cold” and ”hot” refer to the temperature of the
coils. ”Cold” means approximately −10_Cto50 _C( 14 _Fto
1 22 _F). ”Hot” means approximately 50 _Cto 100 _C( 122 _F
to 2 12_F).
(c) Reconnect the camshaft position sensor connector.

INSPECTION PROCEDURE
HINT:
SIf no trouble is found in troubleshooting of DTC P0335 troubleshoot the engine mechanical system.
SRead freeze frame data usingthe hand−held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, if the engine was warmed up or not, if the air−fuel ratio was lean or
rich, and other data from the time the malfunction occurred.
SRead value of hand−held tester
(a) Connect the hand−held tester to the DLC3.
(b) Start the engine and turn the hand−held tester ON.
(c) Select the item: DIAGNOSIS / OBD/MOBD / DATA LIST / ALL / ENGINE SPD.
The engine speed can be observed in DATA LIST using the hand−held tester. If there is no NE signals from
the crankshaft position sensor despite the engine revolving, the engine speed will be indicated as zero. If
voltage output from the crankshaft position sensor is insufficient, the engine speed will be indicated as lower
PRM (than the actual RPM).

HINT:
When several codes for a misfiring cylinder are recorded repeatedly but no random misfire code is recorded,
it indicates that the misfires have been detected and recorded at different times.
Reference: Inspection using oscilloscope
With the engine idling, check the waveform between terminals # 1 to #4 and E0 1 of the ECM connectors.
HINT:
The correct waveform is as shown.
