CKP (Crankshaft Position) Sensor 1
DTC 4-1: No crank pulse
1. Reappearance test
-1. Connect the HDS (Dr. H or Pocket Tester) (page 5-
1) and clear the DTC (page 5-2).
• If the DTC cannot be cleared, continue trou-
bleshooting.
-2. Start the engine and let it idle with no load.
-3. Check the DTC with the HDS (Dr. H or Pocket
Tester).
◆
Does DTC 4-1 appear on the tester?
YES -
Go to the step 2.
NO -
Temporary failure (Disappears)..
2. CKP sensor 1 inspection
-1. Turn the ignition switch OFF and disconnect the
CKP sensor 4P connector.
-2. Measure the resistance between the No. 1
(Brown/Blue) terminal and No. 2 (Orange) terminal
of the CKP sensor side connector.
◆
Is there 970 ~ 1,170
Ω
?
YES -
Go to the step 3.
NO -
Replace the CKP sensor.
3. CKP sensor circuit (PC1P) open-circuit inspection
-1. Disconnect the ECM connector A.
-2. Measure the resistance between the No. 2 (Orange)
of the CKP sensor 4P connector and No. 4 (Orange)
terminals of the ECM connector A.
◆
Is there continuity?
YES -
Go to the step 4.
NO -
Repair open circuit between the ECM and
CKP sensor.
4. CKP sensor circuit (PC1M) open-circuit inspection
-1. Measure the resistance between the No. 1
(Brown/Blue) of the CKP sensor 4P connector and
No. 13 (Brown/Blue) terminals of the ECM connec-
tor A.
◆
Is there continuity?
YES -
Go to the step 5.
NO -
Repair open circuit between the ECM and
CKP sensor.
