Did you clean the Throttle body? That is often the cause of a rough idle.

The Fuel Air o2 sensor on the manifold is often hard to reach, but the downstream o2 sensor after the catalytic converter is easier to get to.

Code P0172 indicates Bank 1 of the engine has a rich fuel mixture. P0175 indicates Bank 2 of the engine has a rich fuel mixture. Engine Bank 1 is the same side of the engine as Engine Cylinder 1. Engine Bank 2 is the opposite side of the engine. A firing order and cylinder location diagram may be needed to see which side of the engine is Bank 1 or Bank 2.
P0172 is triggered by the engine bank 1?"upstream" oxygen sensor and P0175 is triggered by the engine bank 2 "upstream" oxygen sensor. The oxygen sensor alerts your system when the condition is too rich meaning there's too much fuel int the exhaust stream or too little oxygen in the exhaust stream. The symptoms and causes will help you determine the exact issue and how to fix it.
Your bank 1 or bank 2 sensors will be referred to as "sensor 1" or "sensor 2". Sensor 1 refers to "upstream" sensors, or the ones near the engine and before the catalytic converter. Sensor 2 is "downstream" or after the converter.

very old post.
that code is in the FSM buy an FSM
or log in to alldata.com and see true meaning,

i believe this is unique to suzuki and only your car./engine and body.
3.6L v6 , the pregnant version of my 2.5L
change the water pump on this engine sux.. big time.


Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor "B"
Number of Trips to Set Code: 2
Trouble Code Conditions:
Difference between camshaft (bank 1 / exhaust side) position and crankshaft position is out of specified range.
Possible Causes:

• CMP sensor
• CKP sensor
• Signal rotor
• Timing chain
• Timing chain tensioner
• CMP actuator
• ECM

loose chain? or the can be a dead (jammed) tensioner.
if crazy loose it can skip a sproket tooth, do you ignore chain noise?

did you look it up?
alldata.com shows.
it means the engine needs service and inspections here.

hi,my friend, you can try,

Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.

Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).

Inspect the downstream heated oxygen sensor (HO2), replace if necessary

Replace the catalytic converter

Catalyst System Efficiency Below Threshold (Bank 1)

A code PO420 may mean that one or more of the following has happened:

• Leaded fuel was used where unleaded was called for
• An oxygen sensor is not reading (functioning) properly
• The engine coolant temperature sensor is not working properly
• Damaged or leaking exhaust manifold / catalytic converter / exhaust pipe
• Retarded spark timing
• The oxygen sensors in front and behind the converter are reporting too similar of reading

• Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.
• Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).
• Inspect the downstream heated oxygen sensor (HO2), replace if necessary
• Replace the catalytic converter

Hi there,

P0030 = HO2S Heater Control Circuit (Bank 1 Sensor 1) - No.1 Heated Oxygen sensor on bank 1.
P0036 = HO2S Heater Control Circuit (Bank 1 Sensor 2) - No. 2 Heated Oxygen sensor on bank 1

For both of these to trigger on the same bank, means most likely an Open or Short to Ground condition (somewhere on the Bank 1 circuit) stopping the HO2 sensors from reaching their working temperature.

Check the following in this order:

1) Using a multimeter, check 'continuity' of the Oxygen circuit FUSE terminals (don't rely on visual inspection alone) or replace fuse with a known good one.
2) Check for moisture getting into both oxygen sensor connector terminals (bank 1).
3) Check for good connection at Oxygen sensors (bank 1).
3) Have both heated oxygen sensors on Bank 1 tested (ensure their values are to specification).
4) Check HO2 pin-outs of the PCM for correct voltage.

Only replace the HO2 sensors as a last resort (if out of spec).

Then engine department relay centre & fusebox location is behind the washer bottle, but I believe the HO2 sensors are connected direct to the PCM, not a relay.

Cheers,

I assume then that this is a v6. Bank one should be the drivers side (I think) . Sensor 1 would be the one before the catalytc convertor and sensor 2 would be the one after it.

I hope help you with this (rated this help). Good luck.

Yes, If you have dual exhaust pipes coming from the engine, Look on the passenger side exhause pipe, and it will be the 1st sensor on the pipe coming out of the engine.
