Hey i have a question i recently change my civic 2010 o2 sensor bank1 sensor 2 and sensor 1 but the codes are still there before changing the sensors there was code engine coolant temperature sensor malfunction and problem but after i change o2 sensors this code is gone but new codes showed up which is air fuel ratio sensor short range performance problem. And rear air fuel bank 1 sensor 1 circuit out of range high these 2 code are showing with red engine light on scanner but not on dash.

Good stuff, writing this down for future use. Find the sensor heater and ground with an ohmmeter. On the harness find the heater hot with a test light. Find the harness permanent ground with a test light, it is used by the signal output. Then find the harness switched ground by turning on the engine power and a test light. The remaining harness wire is signal.

Another perfect, easy listening vid. I wish you had more time to do these, you're the perfect informed moderator.

Excellent description and explanation. Straight to the point without any fluff. Great video

well i dont know how good it is to test ground a wire that receives a positive voltage signal . always make sure one finds the signal wire with a ohm meter before trying to find the grounds or the power wire . the signal wire is very sensitive and should never be ground or to have any other voltage input .

I understand much better, how O2 sensors work and more importantly how to test them. I have a Tacoma truck, no error codes but, the O2 sensor and catalyst registers won't set. That has stumped everyone, no one knew what to do. I spent a ton of money trying to get at least one of the registers fixed and to set. I finally sit down cleared my mind and decided the forward o2 Sensor needed to be replaced. I got it replaced and the O2 Register set in less than 5 miles. I could get my truck registered now. Several months later the O2 register will not set again. The Catalyst never did even after spending $600 on a new catalytic converter. I'm still mad as hell about that. Smog issues are not fun, not many know what they are doing and just start replacing parts which add up very fast.

Excellent video - generalized, precise and informative!

Nice video dude. Im currently working on why my car feels fast, smooth and quiet one day and lazy, sluggish and grunty another day. It drove me mad. I think my b1 s2 heater element retired early and not allowing ecu to enter closed loop sometimes. I reset the adaptions and feels alot better but goes back to lazy mode again later on.

Hi. When decelerating, my fuel system is in open loop, but once the speed fall anywhere between 20 to 10 mph, for a second I get OL has not satisfied yet conditions to go to CL, then immediately goes into CL using all oxy sensors, while still decelerating down from 20 to a stop. What would that indicate and does need to be done? No codes, no lights. PS: you’re one of the most knowledgeable mechanics and the videos show it all.

Paul had a good question and you got a good idea for a video. We all win!

Love you videos bro! You say on the 4 pin, have 2 grounds and one is constant. My issue is, key off, black is constant and so is my black/blue wire. Prob why im throwing a P0138. The heating element never shuts down.

Great video, keep up the great work

Run for president in 24. You got my vote. That explained everything i needed to know about my O2 issues. Thanx.

Good vid always good info. Best term to use on DC systems is common not ground. Also when you test for restistence across the signal wire and common, the voltage applied from your meter could damage the o2 sensor. Output voltage on o2 sensors are very small. This is what I learned from watching other vids. Not from my own experience, so I don't know how true that is or not.

Very good troubleshooting method. You used logic!

Always love watching your videos. This was really easy and a good way to test o2 sensors; as well as giving people a basic idea as far as wire chasing most connectors/sensors. 👍 Definitely would like to see more of these videos.

Awesome vids dude. Question: could you also measure/question continuity between the signal wire at the plug and to the ECU harness pin that corresponds to that signal wire for the O2 as well? I'm chasing a A/F issue with a 993 Porsche. The O2 sensor is new-3 wire, but wanted to go through the wires from the plug on the harness to verify function. Came across your vids this am. Great info. Keep it up! BTW, I am a recovering Audi allroad owner lol! I had thre over 12yrs. -the last was 6MT that I got up to about 440hp. I sweat cam seals are a maintenance item on the 2.7t motor.

I'm chasing a A/F issue with a 993 Porsche. The O2 sensor is new-3 wire, but wanted to go through the wires from the plug on the harness to verify function." Yes, but you only need to go through the trouble of doing that if the sensor is not working. So, you should check functionality first. Make sure the vehicle is warmed up and running at its normal operating temp. Connect a scan tool and look at the data stream. Find your fuel trims and open/closed loop info on the scan tool. If the O2 sensor is working, you should be in closed loop (the engine has to be running.). Assuming you're in closed loop, check to see if your fuel trim numbers make sense. If they do, you've pretty much proved the sensors are working properly. If you're having a drivability issue and you think its O2 sensor related, bypass your O2 sensors and see what happens. In order for them to work the vehicle must be warmed up and in closed loop. look at the scan tool again while the engine is running. Put your foot on the gas pedal and make it go right to the floor. It has to be wide open, and nothing less. Watch your data stream, and the second you reach wide open throttle, the motor should go into open loop. If the car runs better at when in open loop, the problem is most likely an O2 sensor, or something directly related to them. If no change at WOT when the O2 sensors are bypassed, look elsewhere for the problem. The above info can be applied to any car made after 1996. The procedure is OBD2 compliant, so it doesn't matter what kind of vehicle it is. They all have to work the same by law.

Great work buddy. I am already subscribed to your channel and enjoy it. I have a question: Can you really clean an O2 sensor instead of replacing it. There are a lot of videos out there. I want some reliable opinion, like yours. Thanks.

That's an interesting short hand trick. I've always reached for a diagram before moving forward, which is easy enough if you only work on a few cars. On paper it seems risky to send +12V into the PCM backwards along a signal wire that normally carries only 4.5V of miniscule current forward. However I see that many experienced and respected techs have confidence to do it all the time as a quick test, assuming the protection of resistors and diodes inside the driver. Of course current is limited by the test light resistance. It would be a different story if somebody used a jump wire from the pos side. It takes a little more work to back probe connectors while they are hooked up to measure functional values in a working sensor, especially if confused when the PCM shuts down the heater. Still, it is fun to see waveforms directly if one has the time.

In this video I was only figuring out which wires are which and found the signal wire by finding the other 3 wires, sending only voltage and no current up the signal wire using a test light I strongly doubt would harm the PCM.

@@myRatchets to make your *test light* glow, current MUST flow through it....and if you don't know which wire is which, you really run the risk of cooking something in the pcm...like creating a gap in the ADC for the O2 sensor monitor.

@@myRatchets First, you don't have a choice. You can't just send voltage and not current. When using a test light, treat it like a piece of wire because that's what it is. A test like can easily blow a PCM. Careless techs do it every day. So much so, that shops are starting to ban the use of test lights just for that reason. If you want to be safe get a power probe with DVOM functions. You can touch that to any wire you want, and not have to worry. However, you can just as easily do damage like you can with a test light. Never push the button on a power probe unless you know exactly what you're doing. So, as long as you don't push the button, its a much safer tool to use over a test light.

You have outlined the hard way, the easy way is just to go to the pick & pull yard and clip the connector off of another Toyota of similar year range and match the wire colors
