DTC P0133 DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAVE BEEN RECORDED Have FREEZE FRAME DATA and DIAGNOSTIC MONITORING TEST RESULTS (HO2S related) been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA and DIAGNOSTIC MONITORING TEST RESULTS 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 repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	VERIFY RELATED PENDING CODE OR STORED DTC Turn the ignition switch off, then to the ON position (Engine off). Verify the related PENDING CODE or stored DTCs. Is the DTC P0443 also present?	Yes	Go to the DTC P0443 inspection. (See DTC P0443 .)
3		No	Go to the next step.
4	IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA Is DTC P0133 on FREEZE FRAME DATA?	Yes	Go to the next step.
4		No	Go to the FREEZE FRAME DATA DTC inspection. (See DTC TABLE .)
5	VERIFY CURRENT INPUT SIGNAL STATUS OF FRONT HO2S Connect the WDS or equivalent to the DLC-2. Start the engine and warm it up completely. Access the O2S11 PID. Read the O2S11 PID under following accelerator pedal conditions (in PARK or NEUTRAL). Less than 1 mA when the accelerator pedal is suddenly depressed (rich condition). More than 1 mA just after release of accelerator pedal (lean condition). Is the PID normal?	Yes	Go to Step 8.
5		No	Go to the next step.
6	INSPECT INSTALLATION OF FRONT HO2S Inspect the front HO2S for looseness. Is it normal?	Yes	Go to the next step.
6		No	Tighten the front HO2S, then go to Step 16. (See FRONT HEATED OXYGEN SENSOR (HO2S) REMOVAL/INSTALLATION .)
7	INSPECT EXHAUST SYSTEM FOR EXHAUST GAS LEAKAGE Visually inspect exhaust gas leakage in the exhaust system. Is there exhaust gas leakage?	Yes	Repair or replace the malfunctioning part, then go to Step 16.
7		No	Replace the front HO2S, then go to Step 16. (See FRONT HEATED OXYGEN SENSOR (HO2S) REMOVAL/INSTALLATION .)
8	INSPECT LONG TERM FUEL TRIM Connect the WDS or equivalent to the DLC-2. Access the LONGFT1 PID. Compare the LONGFT1 PID with recorded FREEZE FRAME DATA at Step 1. Is the LONGFT1 PID below FREEZE FRAME DATA?	Yes	Engine is driven under rich condition. Go to the next step.
8		No	Engine is driven under lean condition. Go to Step 10.
9	INSPECT FUEL LINE PRESSURE (EXCESSIVE FUEL LINE PRESSURE) Perform the "FUEL LINE PRESSURE INSPECTION". (See FUEL LINE PRESSURE INSPECTION .) Is there any malfunction?	Yes	Repair or replace the malfunctioning part according to the inspection results. Then go to the Step 16.
9		No	Go to the next step.
10	INSPECT FUEL LINE PRESSURE (LOW FUEL LINE PRESSURE) Perform the "FUEL LINE PRESSURE INSPECTION". (See FUEL LINE PRESSURE INSPECTION .) Is there any malfunction?	Yes	Go to the next step.
10		No	Go to step 12.
11	INSPECT FUEL SYSTEM FOR FUEL LEAKAGE Visually inspect fuel leakage in the fuel system. Is there fuel leakage?	Yes	Repair or replace the malfunctioning part, then go to Step 16.
11		No	Replace the fuel pump unit, then go to Step 16. (See FUEL PUMP UNIT REMOVAL/INSTALLATION .)
12	INSPECT AIR SYSTEM OPERATION Perform the "AIR System Inspection". (See SECONDARY AIR INJECTION (AIR) SYSTEM INSPECTION .) Is there any malfunction?	Yes	Repair or replace the malfunctioning part according to the inspection results. Then go to Step 16.
12		No	Go to the next step.
13	INSPECT ENGINE COOLANT PASSAGE FOR ENGINE COOLANT LEAKAGE Perform the "ENGINE COOLANT LEAKAGE INSPECTION". (See ENGINE COOLANT LEAKAGE INSPECTION .) Is there any malfunction?	Yes	Repair or replace the malfunctioning part according to the inspection results. Then go to Step 16.
13		No	Go to the next step.
14	INSPECT TP SENSOR Inspect the TP sensor. (See THROTTLE POSITION (TP) SENSOR INSPECTION .) Is there any malfunction?	Yes	Replace the throttle body, then go to Step 16. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION .)
14		No	Go to the next step.
15	INSPECT ECCENTRIC SHAFT POSITION SENSOR Inspect the eccentric shaft position sensor. (See ECCENTRIC SHAFT POSITION SENSOR INSPECTION .) Is there any malfunction?	Yes	Replace the eccentric shaft position sensor, then go to the next step. (See ECCENTRIC SHAFT POSITION SENSOR REMOVAL/INSTALLATION .)
15		No	Go to the next step.
16	VERIFY TROUBLESHOOTING OF DTC P0133 COMPLETED Make sure to reconnect all disconnected connectors. Clear the DTC from the PCM memory using the WDS or equivalent. Perform the DRIVE MODE 1 and 3. (See OBD-II DRIVE MODE .) Is the PENDING CODE same as the DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION .)
16		No	Go to the next step.
17	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE .)
17		No	DTC troubleshooting completed.
