DTC P0122 - DIAGNOSTIC PROCEDURE

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 repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Check for related Service Bulletins and/or online 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 CURRENT INPUT SIGNAL STATUS - IS CONCERN INTERMITTENT OR CONSTANT Connect breakout box with PCM disconnected. Turn key to ON (Engine off). Check voltage at breakout box terminal 40 while gradually depressing accelerator pedal. Is voltage below 0.16 V?	Yes	Go to the next step.
3		No	Intermittent concern exists. Go to INTERMITTENT CONCERNS TROUBLESHOOTING procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING .)
4	CLASSIFY TP SENSOR OR HARNESS MALFUNCTION Disconnect TP sensor connector. Connect a jumper wire between TP sensor terminals B and C (harness-side). Check voltage at breakout box terminal 40. Is voltage above 4.9 V?	Yes	Go to the next step.
4		No	Go to step 6.
5	CHECK TP SENSOR CIRCUIT FOR OPEN Turn the ignition switch off. Check continuity between TP sensor terminals B and C (part-side). Is there continuity?	Yes	Check for poor TP sensor connector terminal C connection. Repair or replace as necessary, then go to Step 9.
5		No	Replace TP sensor, then go to Step 9.
6	CHECK POWER SUPPLY CIRCUIT VOLTAGE AT TP SENSOR CONNECTOR NOTE: If DTC P0107 is also retrieved with P0122, then go to CONSTANT VOLTAGE troubleshooting procedure. Turn key to ON (Engine off). Check voltage at TP sensor terminal C (harness-side). Is voltage within 4.5-5.5 V?	Yes	Go to the next step.
6		No	Repair or replace open circuit between TP sensor connector terminal C and PCM connector terminal 33 (harness-side). Then, then go to Step 9.
7	VERIFY TP SIGNAL CIRCUIT FOR OPEN Turn the ignition switch off. Check continuity between TP sensor terminal B (harness-side) and breakout box terminal 40. Is there continuity?	Yes	Go to the next step.
7		No	Repair or replace suspected harness, then go to Step 9.
8	VERIFY TP SIGNAL CIRCUIT FOR SHORT TO GROUND Check continuity between TP sensor terminal B (harness-side) and body ground. Is there continuity?	Yes	Repair or replace suspected harness, then go to Step 9.
8		No	Go to the next step.
9	VERIFY TROUBLESHOOTING OF DTC P0122 COMPLETED Make sure to reconnect all disconnected connectors. Turn key to ON (Engine off). Clear the DTC from the PCM memory using the WDS or equivalent. Is same DTC present?	Yes	Replace PCM, then go to the next step.
9		No	Go to the next step.
10	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 .)
10		No	Troubleshooting completed.
