the sensor probe and heater element are 2 different parts crammed into the nice little casing you see in your hand, so the probe could be fine but the heater element f***ed, easy test would be to switch it with the same one on the other side and see if the problem goes with the sensor or stays on the same side, if it stays then you have a wiring issue. if it goes to the other side then replace the sensor unit.

The oxygen sensor are just refered to as upstream for the o2s and down stream are actually refered to as catalytic monitors. So if you have lean or rich codes these would refer to the upstream .

Hello! I am sending two diagrams...#1 is O2 sensor location and #2 is a vacuum diagram...Before you spend a lot of money replacing O2 sensors lets eliminate other possible causes of heater circuit failure...O2's have heater circuits to bring them up to high temperature quickly so the computer (PCM) will have close control...I would suspect poor grounding, or connector contact corrosion...If you have an ohm meter...Set it on the X10 scale...Measure from center of the negative battery post to the chassis (bare metal)...And then to the engine block...Record both readings...Radio Shack sells a no-touch contact cleaner called DEOXIT...Spray a very small amount on all O2 connectors (male and female)...Oxidation is chemically removed...Re-connect...
Check all vacuum lines for broken, cracked, loose or collapsed...Send results....Guru...Saaileraa07bbb.gif

There are 4 such sensors on your car. this sensor is on the passenger side of the car just below where the exhaust manifold attaches to the exhaust pipe. There is a similar one on the driver's side and the other two are downstream of the catalytic converters. See picture below and let me know if you have more questions.

Hi, no, don't do that. The code 174 indicates a vacuum leak--not a bad sensor. The leak can be anywhere downstream of the mass airflow sensor on the inlet pipe. Sometimes the rubber pipe itself tears/cracks, or maybe there is a loose vacuum hose or a torn brake booster diaphram. Check all the hoses attached to the engine intake manifold for a leak at either end or in between.
If all hoses are good, next check the intake manifold askets for leaks. Get yourself a can of carb cleaner and start the engine. Spray the gaskets all around. If the engine speed changes, you have a gasket leak--replace the gaskets. Since you have a code 174 and NOT a code 171, this is the most likely cause of the problem, because only the rigt bank is running lean. Be sure to check the gaskets on that passenger side carefully.
Last of all, if all that was good, check to see if your EGR valve is stuck open. I have pasted instructions for removing the valve below (from autozone.com). Please let me know if you have questions and thanks for using FixYa.


EGR valve R&R.

  1. Disconnect the negative battery cable.
  2. Remove the vacuum hose from the EGR valve.
  3. On the 4.6L engine, remove the nut and the brake booster bracket.
  4. jturcotte_117.jpg
  5. On the 5.4L engine, remove the DPFE sensor retaining nuts and place the sensor to the side to allow access to the EGR tube.
  6. Disconnect the EGR valve-to-exhaust manifold tube from the EGR valve.
  7. jturcotte_118.jpg
  8. Remove the EGR valve mounting bolts, then separate the valve from the intake manifold.
    1. jturcotte_119.jpg
  9. Remove and discard the old EGR valve gasket, and clean the gasket mating surfaces on the valve and the intake manifold.

To install:
  1. Install the EGR valve, along with a new gasket, on the intake manifold, then install and tighten the mounting bolts.
  2. Connect the EGR valve-to-exhaust manifold tube to the valve, then tighten the tube nut to 25-35 ft. lbs. (34-47 Nm).
  3. Connect the vacuum hose to the EGR valve.
  4. On the 5.4L engine, install the DPFE sensor.
  5. On the 4.6L engine install the brake booster bracket and the retaining nut.
  6. Connect the negative battery cable.

      Tip

      Which Oxygen Sensor Is It?


      There are many inquiries online about which oxygen sensor to change. Oxygen sensor failure codes are very common on a lot of vehicles. With all of today's vehicles having at least two oxygen sensors and many having three or four of them, it can be a little confusing as to which one is causing the problem.

      Before we get into which sensor is which, we need to have a little discussion about oxygen sensor fault codes. There are several different types of oxygen sensor fault codes. Here are just some of the most common ones:

      P0135 "Oxygen Sensor Heater Circuit Bank1 Sensor 1"
      P0141 "Oxygen Sensor Heater Circuit Bank 1 Sensor 2"
      P0147 "Oxygen Sensor Circuit Bank 1 Sensor 3"
      P0152 "Oxygen Sensor Voltage High Bank 2 Sensor 1"
      P0159 "Oxygen Sensor Slow Response Bank 2 Sensor 2"
      P0171 "Oxygen Sensor Lean Sensor 1 Bank 1"
      P0172 "Oxygen Sensor Lean Sensor 1 Bank 2"
      P0174 "Oxygen Sensor Rich Sensor 1 Bank 1"
      P0175 "Oxygen Sensor Rich Sensor 1 Bank 2"

      There are many more possible oxygen sensor codes, but I only listed these to make my point. Many times the oxygen sensor code is NOT caused by the oxygen sensor itself. "Lean" or "Rich" oxygen sensor codes (i.e. P0171, P0174) are usually caused by something other than the oxygen sensor. Something is wrong, causing the engine to run lean (not enough fuel or too much air) or causing the engine to run rich (too much fuel or not enough air). In these cases, replacing the oxygen sensor will not fix a thing. (That is, unless you are trying to fix your bank account from having too high of a balance!) The new oxygen sensor will just set the same code as the original one. This is because the oxygen sensor is not CAUSING the problem, it is only REPORTING the problem.

      High voltage codes (like P0152 above) can be caused by the oxygen sensor wires being shorted to another wire inside the wiring harness. Sometimes these codes are caused by bad grounds where some other component is trying to ground through the oxygen sensor circuit. Again, replacing the oxygen sensor will not fix this! In short, the problem needs to be diagnosed before running out and buying an oxygen sensor.

      Just because a fault code has "Oxygen Sensor" or "O2 Sensor" or "O2S" in its description does not necessarily mean that an oxygen sensor needs to be replaced. Many do-it-yourselfers believe that all there is to fixing the car is to hook it to the "magic box", collect the fault codes and replace the parts the computer tells you to replace. There is nothing further from the truth.

      Fault codes only point you toward which SYSTEM is failing. The system must be diagnosed to find the CAUSE of the failure. If this is not done properly, it will only result in wasting a bunch of your money. This is what you were trying to avoid by doing it yourself!

      So, after reading all of the above, if you think you still want to replace an oxygen sensor, but don't know which one; here is how to figure it out:

      Oxygen sensors are always numbered like this:

      Bank 1 Sensor 1
      Bank 2 Sensor 1
      Bank 1 Sensor 2
      Bank 2 Sensor 2

      Some manufacturers use a kind of shorthand that reads different, but means the same thing:

      Sensor 1/1 or O2s 1/1
      Sensor 2/1 or O2s 2/1
      Sensor 1/2 or O2s 1/2
      Sensor 2/2 or O2s 2/2

      Bank 1 is always the side of the engine where cylinder #1 is located and, of course, Bank 2 is the opposite side.
      On a 4 cylinder engine, there is only one bank and it is always referred to as Bank 1. The exception to the 4 cylinder rule is on certain 4 cylinder engines (specifically, some Toyotas) there are two catalytic converters used. In this case, Bank 1 sensors will still be in the pipe for the catalyst that is connected to cylinder #1 and Bank 2 sensors will be in the other one.

      Sensor 1 is always the "upstream" sensor (the one located BEFORE the catalytic converter).
      Sensor 2 is always the "downstream" sensor (the one that is located AFTER the catalytic converter).
      Sensor 3 refers to the ONLY "downstream" sensor where there are two sensors before the catalyst and only one after the catalyst. On very few vehicles the reference to this reads "Bank 1 Sensor 3".

      If you do not know where cylinder #1 is, then you need to get a diagram of the firing order for your engine. Just post a question on FixYa.com and make sure you give the YEAR, MAKE, MODEL, and ENGINE SIZE of your vehicle and one or more of our experts will be happy to tell you how to find cylinder #1.

      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.

      http://helpforcars.net/obd_codes/codes.php?code=P0037

      It's an O2 sensor according to the above link, and it is bank 1 sensor 2 low, the 2 meaning that it is downstream past the catalytic converter but not on the manifold.

      - Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit open shorted to ground
      - Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
      - Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit
      - Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse
      - Faulty Engine Control Module (ECM) Possible Solution Tech Notes The code means that there is a problem with the heater element circuit of the heated oxygen sensor. Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow, which is a very common problem for this type codes. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors.
      Good luck on this repair.
