    o2 sensor issue. . .

    JDM p13 ecu h22a.. Been through two o2 sensors. Code 1 still. There wiring is correct.. Heater circuit tests correct. But I get nothing input or output ecu side. Can I have a bad ecu or what should I do next. If I reset the ecu once I turn to ignition I get a solid cel. When I jump the ecu I get code 1.

    what kinda sensors are you using?

    ...adjust accordingly

        bosch o2 sensors are crap!
        F22a1-->F22A-->H22A-->auto-2-5spd-->K20 6spd-->F22C 6spd RWD-->4G63 6spd AWD-->K24 6spd????

          I am guessing you forgot to think before that one... but thanks for the useless post.... ecu side I am talking about.. I have the same issue with oem and bosch

            No, it is a widely known fact on here that if you have a Bosch o2 sensor, 99% of the time you WILL get a CEL.

              okay I used a brand new oem one with the same issue. I switched to bosch to make sure it was not just the oem honda one. And honda wont take back another one. I know the honda one would be best but it dosent matter what I have in there I still get the cel.

                you guessed wrong. by the sound of ur OP, you said u were going through O2 sensors. you then stated that you have used an OEM/Bosch/Bosch.

                i simply said that bosch is crap. they are known to go bad/throw codes.

                If my post was worthless/pointless that would mean that you would have already known that about Bosch O2 sensors & their quality...but yet you still used them?? hmmm... ok?

                lemme help you out...despite my worthless posts.

                have you tried to measure the voltage at the ECU??? take a multi-meter and set it to 2v. measure the voltage between A26 and D14 with the ignition switch turned on.

                Voltage should start at 0.4 — 0.5 V when the ignition switch is first turned on, and decrease to below 0.1 V in less than two minutes.

                if there isnt 0.1 V or less when the ignition switch is first turned on
                disconnect the O2 sensor plug and then measure the voltage at A26/D14 again. If there is more than 0.1V then replace the O2 with a new OEM sensor.

                If there isnt more than 0.1V, turn ignition off, take out main D wire harness plug, then turn ignition on and check voltage @ A26/D14 again. if there isnt more than 0.1V you need to grab another known GOOD ECU. ur ECU is prolly poopy then.

                you could also have a short in the white wire between D14 and the white wire on the O2 sensor plug if there is more than 0.1V when u measure with the D plug disconnected.
                F22a1-->F22A-->H22A-->auto-2-5spd-->K20 6spd-->F22C 6spd RWD-->4G63 6spd AWD-->K24 6spd????

                  Yes I have and I do not get a reading...

                  interesting what does removing the plug effect...?

                    nevermind. i tried.

                    go grab a good known ecu. see if it fixes the issue. easier for you.
                    F22a1-->F22A-->H22A-->auto-2-5spd-->K20 6spd-->F22C 6spd RWD-->4G63 6spd AWD-->K24 6spd????

                      just wondering what removing the plug effects? I do not have continuity to ground on a a26
