    Hi Acorn

    How many oxygen sensors are there?

    I believe that I'm experiencing the same problem and should replace. Is it easy to do on your own? Are they easy to get to? Do I need any special tools? From the other response, I'll need a code reader after finishing it up. Thankfully, I know a shop that can clear the warning light, and with your help, I'm looking forward to saving some $$$ to afford gas. Don't forget to vote this year.

My 96 prelude keeps shutting off when hot. What do I do to fix it?

96's are kinda the bad year for our cars being the only obd2 4th gen preludes so for any codes over 43 you have to look it up in the '97-'01 manual. Code 65 is "Secondary Heated Oxygen Sensor Heater Circuit Malfunction (Sensor 2)". Probable causes are an open in the secondary O2 sensor heater circuit or bad ECU. Have you tried resetting the ECU to see if it comes back? If so, you could check for loose wires coming from the secondary O2 sensor in the cat converter going to the 4 pin connector, or if you have access to another ECU I would try to substitute a known good ECU to see if that clears it up. The troubleshooting flowchart is on page 11-79 in the '97-'01 helms manual, and involves checking resistances and for continuity.

I think this could be the code I had on my '96 when I bought it. I tried replacing the secondary O2 sensor, and long story short it was the ECU. Luckily my '96 was still under the extended emmissions warranty, so Honda replaced it for free. I don't think you would be covered under the extended warranty because it was 14 years and under 150k miles. I just barely made it (within a month or 2 and 3k miles) last year.

As far as the engine sounds and rough idle, you could just need a valve adjustment. The secondary O2 sensor just checks the cat to make sure it's working right.

And all auto trans want to move forward when the brake is released.

Check for intake leaks, intake hose leaks, check mass air flow sensor.
02 sensors will keep setting off a lean code until the air problem is fixed.

Well, it would seem that replacing the sensor twice would point to the ECM but not always.
Code 125 means the engine is not reaching operating temp which is needed to put the system into closed loop. Closed loop means the ECM is looking at all of the sensor readings to determine fuel trim level instead of using pre-set values. On cars built in the late 1990s closed loop is supposed to happen within a few minutes of start-up to cut down on emissions.
The code means the temp reading is below 195 degrees for too long, which is usually a faulty thermostat. Once in a while it is a faulty temp sensor.
As for the other 3 codes, there could be a problem with the wiring between the O2 sensor and the computer. And that might be expensive to find. So the dealer may be hedging their bet with the ECM replacement idea.
But that would not address the first code unless you have had the thermostat replaced and the cooling system is ok.

Check engine light

The code is for a slow response for bank 2 sensor one. This is the sensor before the catalytic converter on the side with cylinder 2.
It means the data going to the computer is not within range, not necessarily that the sensor is faulty.
Since you have replaced it twice, I would expect to find a cylinder miss, faulty injector, vac leak, or other problem with the engine.

Check engine code P1135 Toyota Highlander v-6

what you looking at on that code is an o2 sensor, the 1135 is bank 1 sensor 1, that says which o2 sensor it is, since most vehicals, especially new foreigns have more than one, this code refers to the first one in your system so if you follow your exhaust manifold back to your pipes, the first one you see, probally right on the manifold, is the one thats malfunctioning. To change it, simply disconect the plug, and use a o2 sensor socket with a ratchet to remove it, and screw the new one back in and plug it in. Pretty simple, wish you luck.....

Engine light won't turn off, replaced o2 sensors, same code p0154

unhook the battery for about 15 minutes and hook it back up... that should clear any codes and reset the light. if you have an anti-theft radio make sure you know the code for it and how to enter it.
