INSPECTION PROCEDURE
HINT:

Perform troubleshooting of DTC P0335/12, 13 first. If no trouble is found, troubleshoot the engine me-
chanical systems.

Read freeze frame data using    
 Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle
was running or stopped, the engine was warmed up or not, the air±fuel ratio was lean or rich, etc. at
the time of the malfunction.
1 INSPECT CRANKSHAFT POSITION SENSOR(RESISTANCE)
(a) Measure the resistance between the terminals of the
crankshaft posision sensor connector.
Resistance:
985 to 1,600
at cold
1,265 to 1,890
at hot
NOTICE:
ºColdº and ºHotº shown above mean the temperature of
the coils themselves. ºColdº is from ±10C (14F) to 50 C
(122 F) and ºHotº is from 50 C (122 F) to 100 C (212 F).

1READ OUTPUT DTC
(a)Clear the DTC (See page 05±149).
(b) Warm up the engine.
(c) Accelerate the engine to 3,000 rpm for 10 seconds or more.
(d)Read the DTC (
See page 05±149).
