OK:
Spark jumps across electrode gap.
(6) Reconnect the 6 fuel injector assembly connectors.
(7) Reinstall the ignition coil assembly.
NG -- CHANGE TO KNOWN GOOD IGNITION COIL ASSEMBLY AND CHECK SPARK OF MISFIRING CYLINDER
OK -- REPLACE SPARK PLUG See: Powertrain Management/Ignition System/Ignition Coil/Service and Repair/Removal
32. CHANGE TO KNOWN GOOD IGNITION COIL ASSEMBLY AND CHECK SPARK OF MISFIRING CYLINDER
(a) Change the installed ignition coil assembly to a known good ignition coil assembly.
(b) Perform a spark test.
CAUTION:
During the test, disconnect all fuel injector assembly connectors.
NOTICE:
Do not crank the engine for more than 2 seconds.
(1) Remove the ignition coil assembly from the cylinder head.
(2) Install the spark plug onto the ignition coil assembly.
(3) Disconnect the 6 fuel injector assembly connectors.
(4) Touch the spark plug to the cylinder head.
(5) Crank the engine for less than 2 seconds and check for spark.
OK:
Spark jumps across electrode gap.
(6) Reconnect the 6 fuel injector assembly connectors.
(7) Reinstall the ignition coil assembly.

2GR-FE ENGINE CONTROL: SFI SYSTEM: P0327,P0328,P0332,P0333: Knock Sensor 1 Circuit Low Input (Bank 1 or Single Sensor)
DESCRIPTION
A flat type knock control sensor (non-resonant type) has a structure that can detect vibration between approximately 6 kHz and 15 kHz.
Knock control sensors are fitted onto the engine block to detect engine knocking.
The knock control sensor contains a piezoelectric element which generates a voltage when it becomes deformed.
The voltage is generated when the engine block vibrates due to knocking. Any occurrence of engine knocking can be suppressed by delaying the
