5 CHECK SHIELD CIRCUIT
1. Reconnect harness connectors disconnected.
2. Disconnect harness connectors F21, F101.
3. Check harness continuity between F21 terminal 2 and engine ground.
Refer to wiring diagram.
Continuity should exist.
4. Also check harness for short to power.
5. Then reconnect harness connectors.
OK or NG
OK©GO TO 6.
NG©Repair open circuit or short to power in harness or connectors.

Component InspectionNLEC1530KNOCK SENSORNLEC1530S01+Use an ohmmeter which can measure more than 10 MW.
1. Disconnect knock sensor harness connector.
2. Check resistance between terminal 1 and ground.
Resistance: 500 - 620 kW[at 25ÉC (77ÉF)]
CAUTION:
Discard any knock sensors that have been dropped or physi-
cally damaged. Use only new ones.
