INSPECTION PROCEDURE
HINT:
Read freeze frame data using \f \b\f\f
Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, it is useful for determi\
ning whether the vehicle was running
or stopped, the engine was warmed up or not, the air±fuel ratio was lea\
n or rich, etc. at the time of the mal-
function.
1CHECK HARNESS AND CONNECTOR
(a)Disconnect the E12 ECM connector.
(b)Check for continuity between the wire harness side con- nectors.
Standard (Check for short):
Symbols (Terminal No.)Specified condition
FKN+ (E12±1) ± FKN± (E12±2)No continuity
OKGo to step 3

3 CHECK HARNESS AND CONNECTOR(ECM ± KNOCK SENSOR)
(a) Disconnect the E12 ECM connector.
(b) Disconnect the knock sensor connector.
(c) Check for continuity between the wire harness side con- nectors.
Standard (Check for open):

4CONFIRM THE MALFUNCTION DISAPPEAR WHEN A GOOD KNOCK SENSOR IS
INSTALLED
(a)Change the knock sensor to a new one.
(1)Remove the knock sensor.
(2)Install a new knock sensor.
Torque: 20 N m (204 kgf cm, 15 ft lbf)
(b)Clear the DTC (See page 05±5).
(c)Perform the driving test.
(d)Read the DTC using the hand±held tester (See page 05±5).
