2004 honda accord ex V6 check engine light codes p0157 and po158 where is the oxygen sensor in my car?
P0157 says low circuit bank 2 sensor 2 while p0158 high voltage bank 2 sensor? Yes both are bank 2 sensor 2.
My engine runs 123 cylinders
456 cylinders
Front
PmOne oxygen sensor is in front of cylinder 5 and the other is in behind cylinder 2 my car has 4 apparently. Bank 2 refers to the opposite of where cylinder 1 is at regardless of cylinder 2, correct? If so I found one 02 sensor so where is the other sensors or if one has a diagram has them even better there also 2 o2 sensors under my car on the exhaust pipes, dual exhaust? Is bank 1 sensor 1 behind cylinder 2? And bank 2 sensor 1 right in front of cylinder 5? Where are the last 2? And what's the phrase: after the Catalyct converter? Or before?
Try looking it up online. You can double check the engine codes as well as locate a diagram as to where the part should be. It may help if you locate a site that uses the Vin number to verify that they have the correct diagram.
Hi when will you get the idea that you can't fix your car. Even with the correct diagnostic test equipment you would not find the problem. Simple diagnostics are not how it is solved. It comes back to the Honda dealer and a series of codes leading to a diagnostic bible. This will state which codes relate to what is the cause of such failures.
even those of us with the knowledge need the manufacturers handbook in order to diagnose a fault. Sensors of oxygen levels are located in various places all over the engine and exhaust system. At least one before the catalytic converter and one after it. To measure the difference of the gasses go in to those coming out of the catalytic converter. If this is now blocked from 11 years of use and 100k miles of use it may be simply this that needs to be replaced. However without the diagnostic handbook you have no idea.
Before the converter is the 02 sensor between the exhaust manifold/engine and the converter. After the converter is the 02 sensor between the converter and muffler. Bank 2 is nearest the radiator. I'd recommend you have a mechanic change the 02 sensor so you don't end up stripping out the bung hole on the exhaust system.
- Check engine light, open door light, and batterie light all came on and won't go off? 2000 Honda Odyssey I already had the altinator replaced it a month old. The batterie almost a year old. Would the belt need be changed or something else?
- Help me! Code P2A00 Oxygen sensor circuit range/performance bank 1 Sensor 1 2008 honda Crv ex?

- Check engine light turns on for a few days and then turns off for weeks/months? Code P0420 on a 2004 Honda Civic Hybrid? Over the last year my check engine light has come on about 3 or 4 times for a few days at a time and then turns off again for a very long period of time. I know the code means my catalytic converter is below threshold but why would it turn off? Could it be something else? Should I look into replacing it or wait it out? Any advice is appreciated!
- Bought a 2006 Honda Civic ex about a month ago, the check engine light came on and it was throwing code p0133 o2 sensor slow response? Bank 1 sensor 1. Now I checked again and it's a P0171 code as we'll System Too Lean Bank 1 . My friend looked at it and said it's my oxygen sensor. Could that be the reason, and is that way it threw the other code as well? The car runs pretty good, does guzzle has a little.
