CKP (Crankshaft Position) Sensor 2
DTC 8-1: No CKP 2 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 8-1 appear on the tester?
YES - Go to the step 2.
NO -
Temporary failure (Disappears).
2. CKP sensor 2 inspection
-1. Turn the ignition switch OFF and disconnect the
CKP sensor 4P connector.
-2. Measure the resistance between the No. 3 (Brown/
Red) and No. 4 (Gray/White) terminals of the CKP
sensor 2.
◆
Is there 970 ~ 1,170
Ω
?
YES - Go to the step 3.
NO -
Replace the CKP sensor.
3. CKP sensor 2 (PC2M) circuit open-circuit
inspection
-1. Disconnect the ECM connector A.
-2. Check for continuity between the No. 3 (Brown/Red)
terminal of the CKP sensor wire harness side 4P
connector and the No. 21 (Brown/Red) terminal of
the ECM connector A.
◆
Is there continuity?
YES - Go to the step 4.
NO -
Repair open circuit between the ECM and
CKP sensor 2.
4. CKP sensor 2 (PC2P) circuit open-circuit inspec-
tion
-1. Check for continuity between the No. 4 (Gray/White)
terminal of the CKP sensor wire harness side 4P
connector and the No. 12 (Gray/White) terminal of
the ECM connector A.
◆
Is there continuity?
YES - Go to the step 5.
NO -
Repair open circuit between the ECM and
CKP sensor 2.
