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).

DTC P0328/52 KNOCK SENSOR 1 CIRCUIT HIGH INPUT
(BANK 1 OR SINGLE SENSOR)
CIRCUIT DESCRIPTION
A flat type knock sensor (non±resonant type) has the structure that can detect the vibration in a wider band
of frequency from about 6 kHz to 15 kHz and has the following features.
Knock sensors are fitted on the cylinder block to detect the engine knocking.
Sensor contains a piezoelectric element which generates a voltage when it becomes deformed, which oc-
curs when the cylinder block vibrates due to knocking. If engine knocking occurs, the ignition timing is re-
tarded to suppress it.
