Apr 01, 2007 5:25 pm - is this really true? I have alot of experience at hand and i find it disgusting that the majority gave this a 3.5 rating. Heres my reasoning, Open up the fuse box of your car. Read the fuse map and you may realize that the ECU has a fuse. By sticking a pin through the 02 sensor wire, its just going to jump 3 volts acrossed the 2 or 3 wires depending on the grounding and 02 sensor heater setup. By cutting the 02 sensor wire, you are cutting it off from the computer system. A car will run without the 02 sensor plugged in. Youre just gonna inconvenience them by making them have to splice the 02 sensor wires or replace one ($50-$200). Learn your shit. Ive already made an egg on ruining components within the car and this is not a way to do it.

Apr 01, 2007 5:32 pm - if you were able to replace the fuse with a solid wire connecting the two and then find out which 02 sensor wire (multiple) was the recieving side from it than you could screw up their ECU but chances are, youll burn up a wire or have a short somewhere through the system long before the power even makes it to the ECU.

Apr 01, 2007 5:35 pm - ^Dude, did you read the whole egg? I said to connect the spark plug wire to the o2 sensor wire... The one that goes directly to the computer (No fuses). That’s 35kv minimum bouncing around the circuit board that’s made to handle 5 to 14v. I’m no electronics genius, but I do believe this would kinda put a damper on the computer’s functionality.

Dodge

Apr 01, 2007 5:46 pm - As for multiple wire O2 sensors, yeah. Newer cars sometimes have them. Most older cars have the one wire system. And 40kV won’t melt the wire, the current is too low.

chickgriddles

Apr 01, 2007 6:39 pm - you said older and newer. EFI has been around since the 80s. 99% of the fuel injected engines ive worked on built before 1990 have 3 wires. They can be differently setup but theyll always have multiple wires. for american and european, theres usually a ground, ECU, and heater (battery). If your gonna actually do this than youre gonna have to follow the wire to battery (not always easy), follow another wire to a part of the chassis (not always easy) and follow the other one to the ECU. All i know is that there is a fuse right on the ECU from the 02 sensor to my car, theres an entire ECU in fuse in the fusebox, and an ECU out fuse in the fusebox. So for this to work on 60% of the cars out there, the power is gonna have to burn out 2 fuses before it reaches the ECU.

Dodge

Apr 01, 2007 6:58 pm - On my 1990 Suburban, there’s one wire going from the o2 sensor straight into the firewall. From there it goes behind the glovebox, and into the ECU. On my old Geo Metro, 1 wire... My Monte Carlo, 1 wire, Pontiac Grand Am, 1 wire....

Dodge

Apr 01, 2007 7:01 pm - And, when you’re dealing with a voltage that high, a fuse ISN’T going to stop it. The voltage is high enough to bridge the gap between the blades of the fuse, IF it even blows...

chickgriddles

Apr 01, 2007 7:08 pm - all of those cars deserve to have their ECUs blown anyways. its just unusual that the spark plug wire is insulated so much like that, but some wires on an alligator clip can handle the same? I just used some monster speaker cable wire and ran it from my 20KV transformer to the neon backlight from my car and it burned the wire right up. Im not saying that you cant do this, im just saying that the practicality of it, the chances of it truly working and the amount of time required is going to make it fail more times than not.

Dodge

Apr 01, 2007 7:34 pm - This isn’t built for longevity. All you need is a spike of high voltage to fry the ECU... The reason the insulation on plug wires is so thick is because of the tendency for high voltage to jump through the insulator. The reason power companies run 10,000+ volts on the high tension lines is because increasing the voltage decreases the amperage, which allows them to run longer distances with less loss (heat). They also use alternating current, which further reduces the losses, because twice during the cycle, there’s no voltage. This is like the pulsing of a plug wire. Shorter duration allows more voltage through. Try this, take an 18ga. wire and swipe it across the terminals of a battery. It’ll spark, but the duration’s so brief, the wire doesn’t melt. With your neon transformer, the wire wasn’t insulated enough. The light probably worked for a short time, then the wire fried. There was probably arcing through the insulation somewhere along the line.... which will also lead to transformer failure. Any high voltage lines that you want to last has to be properly insulated. Quote: all of those cars deserve to have their ECUs blown anyways. Hahaha.... No. It’s based on the owner, not the car. I wouldn’t do this just because of the make/model.

Apr 01, 2007 8:49 pm - There’s plenty of cars with single wire O2 sensors- (random Google search, not nearly a complete list) 92 Toyota MR2 92 Mazda MX6 (Non-turbo) 85 VW Vanagon 91 Ford Escort GT 84 BMW 325e 90 Acura Integra GS 83 VW Rabbit 89 Nissan S13 Silvia 86 Buick Grand National 93 Chevy Camaro Z28 80 BMW 733i 99 Saturn SC2 (foreward mounted) 83-85 Chevy Caprice 94 Chevy Camaro There’s more, but w/e. If you’re not sure, do a simple Google search on the year/make/model of the car.

chickgriddles

Apr 02, 2007 3:24 pm - the 83 volkswagen rabbit has multiple 02 sensor wires. I own one. The It doesnt matter what model you have, vw engines have 2-3 wires. CIS-E, G60, 1.8 8v, 2.0 16v, VR6 12v and 24v, and the 2.0 8v. This includes Vanagons as well. They usually have 1 cable going into it which is really 3 wires combined together that goes in in 1 spot on the 02 sensor and 3 terminals in the ECU.

Apr 02, 2007 3:26 pm - another thing to add is that i did a vacuum check on an 86 grand national today and it has a 2 wire 02 sensor.

Dodge

Apr 02, 2007 3:56 pm - Okay... That’s 3 out of 16 vehicles. All the cars and trucks I’ve owned have had the one wire system, other than my wife’s minivan. Dude, you know cars... Admit there’s a decent amount of cars with the one wire O2 sensor... I have seen the multiple wire o2 sensors. I agree they’re out there. I agree it would be harder to do on a vehicle with one of these multiple wire O2 sensors. If you want to get revenge on someone by messing with their car, it pays to know what they have. I agree you should look up what system you’re dealing with on the net before you go to do this. If you look it up, you can find out which is the signal wire on the heated sensor. It’s not that hard.

chickgriddles

Apr 02, 2007 4:18 pm - yeah i gave you a 5 on your egg anyways but i was just saying that many of the 02 sensor systems that appear to have 1 wire actually have 2 or 3 inside of the casing. They usually group 3 wires together and wrap them in a silicone or heat shrink casing to keep them together and to prevent the wires from tangling, loosening and touching hot parts of the car (downpipe,manifold,ca ). My friend replaced the 02 sensor on his caprice 3 days ago and it is 3 wires grouped in a silicone heat resistant tube. I was just saying that you really do need to do alot of research on the car you do this to before trying it. And it is reccomended that you use a jumper cable to prevent wire shorting. theres a chance that the voltage could jump through a fuse but the fuses in the ECU of my car are glass tube-type and the electricity would need to jump about an inch.

Apr 02, 2007 4:50 pm - ^You commented while I was researching.... But here’s what I got... There are multiple possibilities for any given car.... . AutoPartsWareho se.com-Click on the images to see part detail... . 75-87 Rabbit- First and third o2 sensors are one wire for 79-87 VW Rabbit and 75-84 Rabbit... The middle one is for the California emissions rabbits. . 85 VW Van- Most of the sensors are clearly single wire. One is multiple wire, but if you read the text in the image, it says Image may not be application specific. ...... 86 Buick GN- Too many sensors to list, but click on the images of them, half are single wire. Same for the GNX, BTW.... . Thanks for the five...

chickgriddles

Apr 02, 2007 4:56 pm - you are talking about replacement sensors. The ones that come stock on a car are usually multiple wires. And the DIGI-1 emissions for the vw rabbits for california emissions were multiple wire, as well as the DIGI-2 so all of them had multiple wires. Cheap replacement sensors will cut out the lead from the battery to the heater so they will have single wires. Higher quality OEM replacements such as bosch will have multiple wires just as the shop manual says to replace. Thats why they always say to buy the right one rather than some cheap-o single wire setup.

Dodge

Apr 02, 2007 5:06 pm - The three that Auto Parts Warehouse offers for the Rabbit are OEM Bosch... not universal, and the two that say OEM on the van list are 1 wire Bosch... Bah... w/e... I’m tired of arguing... (Just noticed your avatar... LOL)
