Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT CKP SENSOR CONNECTOR CONDITION • Turn the ignition switch off. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 11.
3		No	Go to the next step.
4	INSPECT CKP SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT • CKP sensor connector is disconnected. • Inspect for continuity between CKP sensor terminal A (wiring harness-side) and body ground. • Is there continuity?	Yes	Go to the next step.
4		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 11.
5	INSPECT CKP SENSOR CIRCUIT FOR SHORT TO GROUND • CKP sensor connector is disconnected. • Inspect for continuity between the following terminals (wiring harness-side) and body ground: ― CKP sensor terminal C ― CKP sensor terminal B • Is there continuity?	Yes	If the short to ground circuit could be detected: • Repair or replace the wiring harness for a possible short to ground. If the short to ground circuit could not be detected: • Replace the PCM (short to ground in PCM internal circuit). (See PCM REMOVAL/INSTALLATION [L5].) Go to Step 11.
5		No	Go to the next step.
6	INSPECT PCM CONNECTOR CONDITION • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 11.
6		No	Go to the next step.
7	INSPECT CKP SENSOR CIRCUIT FOR SHORT TO POWER SUPPLY • CKP sensor and PCM connectors are disconnected. • Turn the ignition switch to the ON position (engine off). • Measure the voltage at the CKP sensor terminal B (wiring harness-side). • Is there any voltage?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to Step 11.
7		No	Go to the next step.
8	INSPECT CKP SENSOR CIRCUITS FOR SHORT TO EACH OTHER • CKP sensor and PCM connectors are disconnected. • Turn the ignition switch off. • Inspect for continuity between CKP sensor terminals C and B (wiring harness-side). • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to each other, then go to Step 11.
8		No	Go to the next step.
9	INSPECT CKP CIRCUIT FOR OPEN CIRCUIT • CKP sensor and PCM connectors are disconnected. • Inspect for continuity between the following terminals (wiring harness-side): ― CKP sensor terminal C—PCM terminal 2AQ ― CKP sensor terminal B—PCM terminal 2W • Is there continuity?	Yes	Go to the next step.
9		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 11.
10	INSPECT CKP SENSOR • Turn the ignition switch off. • Inspect the CKP sensor. (See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [L5]) • Is there any malfunction?	Yes	Replace the CKP sensor, then go to the next step. (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION [L5].)
10		No	Go to the next step.
11	VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [L5].) • Start the engine and warm it up completely. • Access the MAF PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [L5].) Note • The MAF PID should indicate 1.95 g/s {0.25 lb/min} or above during this test. • Perform the KOER self test. (See KOEO/KOER SELF TEST [L5].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L5].)
11		No	Go to the next step.
12	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [L5].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [L5].)
12		No	DTC troubleshooting completed.
