SOURCE: getting a code #P0038

bank #1 sensor 2 down stream that's after exhaust manifold! I would change both to assure fuel efficiency and economy and they are part of 80thousand to a 100 thousand km service that should be replaced if you replace just the 1 that is gone I guarantee the up stream bank 1 sensor 1 will go almost immediately shortly after save and do it right first time but it is your call these switches work together!!!!I would hope this helps you will need a 22mm wrench to get it off from passenger side under seat area under the car the wire is about3 feet long best to go OEM don't go universal to save 10 bucks you have to cut and join wires not a good seen they will short out eventually so go OEM plugs in perfect thats the way to go the wire snaps in to seat of inside of alternator have fun don't forget to disconnect battery to reset computer while installing!John/Toronto Canada

SOURCE: Want to know what PO172 System too rich bank 1

it means your cars computer is pumping too muchgas into your motor because it thinks the engine is either running lean possibly due to faulty o2 sensors or that the coolant temp sensor is giving false readings and the ecm thinks the car is still too cold.

Your heated O2 sensor has a heeater problem most likely. Most likely time to change out your HO2 sensor. Most cars actually have only primary heated. Not sure for this application but would thus assume the primary sensor or otherwise known as precat O2.
With a sensor high you have high voltage back to the pcm thus most likely shorted heating element.

There is an outside chance of a cross short to the ground circuit of your O2 sensor. If after replacing your sensor you still have a problem then start looking for this.

I see you went to the auto parts store and got an HO2 sensor (Should be a 22mm or 7/8" -- same size) and replace the Primary and if that do not solve the problem, then see if you have a heated postcat HO2 if not then see above.

Good luck and hope this helps, oh and Bank 1 is where your #1 cylinder is.

#1 is the drivers front. The O2 your looking for is on the drivers side after the catalytic converter. You can certainly try to repair the wire. If you use a **** style connector make sure it is one with a heat shrink wrap to protect the wiring from corrosion. The best repair would be to solder the connection and then shrink wrap the joint. If the repair doesn't work you're only out a couple of bucks.

P0038 of my Toyota Tacoma 2005


Parts swapping by code definition is reasonably good gambling, but it is in fact gambling. Your code was for bank 1 sensor 2 heater circuit stays HIGH. That means there is a short to voltage or low resistance in the load side. (The sensor itself). If you changed the sensor with a NEW AND CORRECT PART...that is key BTW, there are a few different sensors in the world that share plug shapes and have different values. But that aside, you need to test the power input to the heater and see what its doing and then the PCM ground and see what ITS doing. The code can be set if there is power when there shouldnt be, or if the ground side cannot pull the circuit to ground...which is either a failed load (low resistance/uncontrolled amperage exceeding the capability of the driver) OR the driver itself has melted (seen it a few tymes) or a 12v wire has rubbed through and is shorting to the heater ground and holding it high. This is what a technician will check next.

Its not a P0300 it's P0032 and P0038


code p0032refers to heated oxygen sensor(HO2S) 1 bank 1-heater control--circuit high===causes --wiring short to positive--HO2S sensor--ECM
code p0038 refers to heated oxygen sensor(HO2S) 2 bank1 heater control --circuit high===causes --wiring shorted to positive --HO2S---ECM
It is most important that when installing /removing the sensor that the correct tool is used to prevent damage to the wiring for the sensors. Severely twisting the wires during installation/ removal will result in the causes for failure listed.

The oxygen sensors on your truck have an extra wire to them,they are a heated oxygen sensor,
the computer sees a problem with the heated oxygen sensor on the drivers side,before converter.

Bank 1 sensor 2. Oxygen sensor heater control circuit high. You can try disconnecting at connector to sensor, clean connection good, disconnect battery for a minute or so & retry. If it comes back, I'd look at replacing heater solenoid.
