P1167 check engine light comes on with a p1167 stored in memory cant find a dignostic chart.O2 sensors appear to be switching fine cant find any exhaust leaks or vaccum leaks.

Please read about this fault code and its possible sources. P1167 Hyundai O2 Sensor System Lambda Controller at the Limit Bank 2

P1166 pertains to the upstream O2 sensor heater circuit. P1167 pertains to the upstream O2 sensor output.

Start by changine the one closest to the engine. Probably in the exhaust manifold right in the engine bay. Recommend you buy OEM, as I've heard of people having issues with aftermarket sensors.
There's also a fuse for the heater circuit in the O2 sensors that could be blown, but I'd bet it's just a bad sensor.

Check o2 heater fuse and relay 1st.

This has nothing to do with the O2 sensor, this is the A/F sensor in the exhaust manifold

DTC P1167: A/F Sensor (Sensor 1) Heater System Malfunction

NOTE: If DTC P1162 is stored at the same time as DTC P1167, troubleshoot DTC P1162 first, then troubleshoot DTC P1167.

Reset the ECM/PCM.
Start the engine. Wait for at least 80 seconds . Is DTC P01167 indicated? YES - Go to step 3. NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at C102 (located under the under-hood fuse/relay box), the A/F Sensor relay, the A/F Sensor (Sensor 1), and the ECM/PCM.
Disconnect the A/F Sensor 4P connector, and ECM/PCM connector C (31P).

Connect ECM/PCM connector terminals C14 and C15 to body ground with a jumper wire.

Check for continuity between A/F Sensor (Sensor 1) 4P connector terminal No.1, No.2, and body ground individuality. Is there continuity? YES - Replace the A/F Sensor (Sensor 1). NO - Repair open or short in the wire between the A/F Sensor (Sensor 1) and the ECM/PCM (C14 or C15).

The O2 sensor is located on the exhaust pipes.Be sure you change out the right one as some vehicles will have 4 of them others maybe 3 make sure you are replacing the right one.

Hello there:
P1167 and P1166 codes relate to the primary O2 sensor heater malfunction.
there are two different O2 sensors, a "universal" sensor from Autozone and a supposedly OEM sensor from O'Reilly's. Both of them may cause the car to throw a p1166 or P1167 code and run rough. so i highly recommend getting a O2 sensor from Honda, and this will fix the problem .
It turns out that none of the aftermarket probes from Bosch or Denso will work on a ULEV (F23A4) 4 cyl. engine. Honda had different part number probes for the normal VTEC 4 cyl. and the ULEV Vtec engine and the probes look different and have different length cables. The computers at O'Reilly's, Autozone, or NAPA made no distinction between these two engine types.

The DTC (Data Trouble Code) P0135 is for the O2 sensor Heater Circuit Bank 1 Sensor 1. Bank 1 will always be the cylinder bank with the number one cylinder and spark plug, and the number one O2 sensor will be located before the catalytic converter and usually at the rear of the exhaust manifold or just after it. According to the firing order diagram bank one is the cylinder bank that is closest to the fire-wall and there should be an O2 sensor located there around the rear of the exhaust manifold or just after it. If the engine is a 4 cylinder then it will be the O2 sensor before or up-stream of the catalytic converter. Check for any damaged wiring or loose wire connector at the O2 sensor and if they are alright then replace the O2 sensor and then re-set the check engine light. (The auto part store should re-set the check engine light for you if you purchase the O2 sensor from them, and be certain that it is the correct and assembled O2 sensor for your vehicle and not a put together universal O2 sensor)

Trouble Code: P01167

HO2S-11 Controller Adaptive Test (Bank 2)

HI, this code represents a fault within one or both of the O2 sensors that are located on the exhaust system i will list the possible causes of this code you are receiving.


Possible Causes:

Air leaks after the MAF sensor, or in the EGR or PCV system

Base engine "mechanical" fault affecting one or more cylinders

Exhaust leaks located in front of the A/FS or HO2S location

Fuel control sensor is out of calibration (i.e., ECT, IAT or MAP)

Fuel delivery system supplying too little fuel during cruise or idle periods (e.g., faulty fuel pump or dirty, restricted fuel filter)

Fuel injector (one or more) dirty or pressure regulator has failed

HO2S is contaminated, deteriorated or it has failed

Vehicle driven low on fuel or until it ran out of fuel

Sensor Contamination Inspection 1. Visually/physically inspect following items: A. Remove and inspect the HO2S(B1S1) for any silicon contamination. This contamination will be indicated by a white powdery coating and this will result in a but false voltage signal. B. Check MAFS for contamination, deterioration, or damage. C. If contamination is evident on the HO2S or MAFS, replace contaminated sensor and go to next step.
