Diagnostic procedure

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Service Bulletins and/or on-line repair information availability. Is any related Service Bulletins available?	Yes	Perform repair or diagnosis according to the available Service Bulletins. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT IAT SENSOR CONNECTOR FOR POOR CONNECTION Switch the ignition to off. Disconnect MAF/IAT sensor connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Are there any malfunction?	Yes	Repair or replace suspected part, then go to Step 9.
3		No	Go to the next step.
4	CLASSIFY IAT SENSOR MALFUNCTION OR HARNESS MALFUNCTION Disconnect the MAF/IAT sensor connector. Switch the ignition to ON (Engine off). Measure voltage between MAF/IAT sensor terminal F (wiring harness-side) and body ground Is voltage 4.5-5.5 V ?	Yes	Inspect the IAT sensor. (See INTAKE AIR TEMPERATURE (IAT) SENSOR INSPECTION [MZI-3.7] .) Replace if necessary, then go to Step 9
4		No	Go to the next step
5	INSPECT IAT SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY Switch the ignition to ON (Engine off). Measure voltage between MAF/IAT sensor terminal F (wiring harness-side) and body ground. Is voltage B+ ?	Yes	Repair or replace suspected part, then go to Step 9
5		No	Go to the next step.
6	INSPECT PCM CONNECTOR FOR POOR CONNECTION Switch the ignition to off. Disconnect PCM connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Are there any malfunction?	Yes	Repair or replace suspected part, then go to Step 9.
6		No	Go to the next step
7	INSPECT IAT SENSOR SIGNAL CIRCUIT FOR OPEN CIRCUIT Inspect continuity between MAF/IAT sensor terminal F (wiring harness-side) and PCM terminal 1P (wiring harness-side). Is there continuity?	Yes	Go to the next step.
7		No	Repair or replace suspected part, then go to Step 9
8	INSPECT IAT SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT Inspect continuity between MAF/IAT sensor terminal E (wiring harness-side) and PCM terminal 1AT (wiring harness-side). Is there continuity?	Yes	Go to the next step.
8		No	Repair or replace suspected part, then go to the next step.
9	VERIFY TROUBLESHOOTING OF DTC P0113:00 HAS BEEN COMPLETED Verify that all disconnected connectors reconnected. Switch the ignition to ON (Engine off). Clear the DTC from the PCM memory using the M-MDS. Start engine and warm it up completely. Is same DTC present?	Yes	Replace the PCM, then go to the next step (See PCM REMOVAL/INSTALLATION [MZI-3.7] .)
9		No	Go to the next step
10	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE" (See AFTER REPAIR PROCEDURE [MZI-3.7] .) Are any DTCs present?	Yes	Go to the applicable DTC inspection (See DTC TABLE [MZI-3.7] .)
10		No	Troubleshooting completed.
