Sigh...google...if it's not too much of a bother. Take a hacksaw blade and grind it into a key extractor. Dental pick. Toothpick with a drop of super glue on the end. On and on. Even when connected to the greatest source of information mankind has ever known one still has to use one's bean.
Well, that's the first post you've made in this thread that actually describes the symptoms. You need to get closed loop working first. Do what I said before. Run the engine at 2500 rpm and check Vf both with the jumper in and out.
I'm a bit embarrassed to admit this but when I was 15 I pestered my Dad into driving 100 miles to buy my first Fluke. It was an LED bench model. Cost me $150 new. I saved months for it. Pretty sad huh? It's gets worse. That was during my sophomore year in a vocational technical high school. It...
You should see my other stuff. I'm a serious metrology freak ;)
469: The aforementioned 87III is a fine instrument. You can get one fairly cheap on ebay if it comes to that. Be sure it has the LCD and white lighting upgrade. If not they can also be had on ebay. Err, or maybe the IIIs already...
I have a Fluke 87V and a Tektronix TX3. The Fluke 88 is for designed for automotive use. Nice but not required. I also have a Fluke 120 Scopemeter and a Fluke 867 Graphical Multimeter. Although the last two are expensive instruments the 80 series are great meters and would serve you well for...
Careful. That statement refers to the emulated O2 signal taken from Vf when *not* in learned value mode. Vf outputs learned value only when T1 and E is unconnected. The test procedure written above for checking the O2 sensor is with the jumper installed. The meter may be connected to Vf but it's...
Ugh. Had I done what I usually do and used the "find all posts by" feature I'd have known how ignorant this guy really is. Nothing tells the tale like a history of NFI. Not to mention comparing something like global warming to easily measured urban air quality (hell, people can see it) doesn't...
Well, you probably could run without it and not have problems. Lots of people do. Moral and legal issues aside (a study released today shows 50% of the US population still lives in unhealthy air) you'd likely never notice. Doesn't mean it would be the right thing to do from a tech standpoint...
It's all good. We're all here to be helpful. Just that I feel substitution is a poor method of troubleshooting. It can be expensive, frustrating and is something people who take pride in their diagnostic skills are loath to do. Another point is not everyone who reads this forum is a parts...
Pretty funny. I have no dog in this fight. All I'll say is 1) Stating "facts" based on one's own personal experience is a logical fallacy and 2) The EVAP system in the Supra, as in most cars, is designed to keep the tank at a positive pressure to help reduce fuel pump cavitation. It's not just...
Maybe that's why you're on here asking for advice eh? Monkeys can swap parts, especially poor monkeys who got that way by needlessly replacing good ones. Cuts into money that can be spent on bananas. Nuff said.
The first test can be used to troubleshoot all kinds of other problems....
If that's all that's wrong with the car buy it. Not a hard problem to fix.
Code 14 happens when the ECU doesn't get a confirmation spark occurred after it was commanded. It'll then shut down fuel injection to prevent hydrolock and catalyst overheat. Your problem is very likely in the ignition...
With the sensor disconnected the system is in open loop so Vf will be zero.
O2 sensor test on the car:
1) Warm the engine up.
2) Connect your meter to either Vf or Ox. Connect the other lead to battery negative. If Vf set the meter to read 5 volts and jumper T1 and E. If Ox set it to...
I've read enough to know you're electrically fluent so I'm not saying you're wrong either. That's why I said "in theory".
It may be wired like one but I said it doesn't operate like a DC series circuit. The thing is you're looking at it like it is one, needing a return path. That may well be...
With the engine at TDC on the compression stoke install the CPS with the groove and drill mark aligned and the slot on the CPS centered on bolt hole on the head:

You can also line up the groove and drill mark and use a pencil or sharpie to mark across the rotor and...
