SOURCE: getting code p1135 and p1155 on toyota rav4

Here's what the codes mean:
P1135 Air/Fuel Sensor Heater Circuit Response (Bank 1 Sensor 1)
P1155 Air/Fuel Sensor Heater Circuit. (Bank 1 Sensor 2

This is mainly related to the oxygen sensors. It maybe the sensors themselves or an open wire going to te sensors. They are mainly located on the exhaust pipe. One before and on after the catalytic converter.

SOURCE: how to repair po420 code on a 2002 toyota sienna

The P0420 code is Catalyst System Efficiency Below Threshold (Bank 1) error.
A code P0420 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 readings
Some suggested steps for troubleshooting a P0420 code include:
  • 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
One thing to note is that many vehicle manufacturers
offer a longer warranty on emissions-related parts. So if you have a newer car but it's out of it's bumper-to-bumper warranty, there still may be warranty on this type of problem. Many manufacturers give a five year, unlimited mileage warranty on these items. It's worth checking into.

I am having a multiple cylinder misfire on my 2006 Toyota RAV4 with the 3.5L V6. Every cylinder is reporting a mifire. Each cylinder has it's own coil. I highly doubt that all 6 coils went bad at once. Does anyone have any idea what my be causing this?? Is that the problem you two are having?

The most probable cause would be blocked system. However code p0420 refers to catalytic converter system bank 1--efficiency below threshold===causes--catalytic converter faulty---wiring ---HOS2. It is more likely that the oxygen sensor needs attention and the cat converter needs replacing

2002 toyota rav 4 / code po420 whats wrong ?


You have a cat converter ie eficiency code. Most shops are willing to sell you a cat converter and make a quick buck. However you can save some major money if you can find out what is wrong. A cat converter doesn't just go bad by itself something causes it to fail. Most likely a bad oxygen sensor or a dirty mass air flow sensor. I would replace the oxygen sensor in front before I replace converter. Reset check engine light and see if light comes back on. If it stays off you just save about 600 dollars. Oxygen sensors cause cat converters to go bad. So fix the cause first, then if you have to replace converter.
