Need Wideband bandaid. Ideas?
My wideband heater circuit is stuck at .78V. Im getting 12v on power + so its the other end of the circuitry. If I just wire it to 12v and ground power -. Will the sensor just overheat or will it stabilize at an overdriven amount which can be corrected with a free-air calibration. I need to get at minimum 30 minutes though 4 hours would be great. ideas rants anything. need it asap

Nothing which you have written here makes any sense to me. My wideband heater circuit is stuck at .78V. I literally have no idea what you are attempting to convey here. I need to get at minimum 30 minutes though 4 hours would be great. What sensor are you using? Where are these measurements coming from? What does "30 minutes though 4 hours" mean? What, specifically, are you asking us for? |
yes sorry. Its been a long day.
My Wideband 02 will not heat up and thus not provide accurate AFRs. The issue is with the heater circuit controlling the WB. I would like to bypass the heater circuit entirely. As long as I can keep the sensor heated I can calibrate it and use it. If I can keep the WB working for one tune then ill be happy. WB Sensor is a 24300 L2h2. There are two power wires + and -. + is battery voltage - is controlled by the heater circuit by PWM. Keeping the sensor not too hot or too cold. The circuit has failed and im looking for a workaround to get me through 1 tune. |
Which gauge/controller?
