code 176, 452

[Mikey]

Think i got these right 176 is front bank lean and 452 is vehicle speed sensor. I have a catless Y and was told that it can cause the C\E light to come on because the o2's dont get hot enough.Both o2s are new also. Is there any truth to that and if so how do i remedy the problem. I also ended up damaging all four Vehicle speed sensors because they were so seized into their holes that the amount of force required to take the front two out that it cracked them, and i just cut the back ones out because i had to use my 89 parts car rear hubs whwn replacing springs and shocks because one of the 93's were damaged. I have a feeling i may have done a bad thing but a little relief that the 89 doesnt have abs shrug My question is will the vss problem not allow the computer to go to open loop, (open loop is when the car is warm and reads from the sensors right, please correct me if i'm wrong). Tommorow i'm gonna check for vaccum leaks concerning the leaks and take it from there. Thanks Everyone

I believe you are mistaking the Vehicle Speed sensor for something else. THe SHO is only equipped with one and it is located on the Speedometer cable, below the Drivers side rear corner of the intake manifold.

What ever you did, it sounds bad.

Well what are the sensors that are over the axle rings with teeth and the sensors on the back hubs of the 93 that have the teethed ring on them. It is a MTX also.

Those were the ABS wheel sensors. Now you don't have ABS on this car, either.

Whoever told you that about the O2 sensors and the cat-less Y-pipe didn't have a clue. It doesn't work that way.

Open/closed loop control by the computer is dependent on the engine coolant temperature as reported by the ECT sensor. Has nothing to do with the VSS. On an MTX, the VSS has little to do except be used for the cruise control.

Focus on the intake/vacuum leaks for the 176 code as you indicated since the sensors are "new".

Thanks for the info guys, I would be kinda happy if the abs didnt work, it is not fun in the snow in pa when trying to come to stop on a slick downhill. So the vehicle speed sensor is the plug mated to the link on the speedometer cable that goes into the tranny? Thanks for the info on the catless' y not causing the code bs , this i'm glad about too cause i like it to much, so now it can stay. Oh yea and dont go to R&S custom exhaust this guy wouldnt even do any exhaust work unless i put the cats back madflame , good thing there's cat backs for the show. ****

Mikey,

For your information, and others, the custom exhaust shop you mentioned is obeying the law. Professional mechanics, including exhaust shops, can be VERY HEAVILY fined for TAMPERING with any part of the emissions control devices, including the cats.

The exaust shop was doing the right thing, according to the law. Would you be willing to pay his $25,000 fine to the Federal Government? Then there is the State EPA that could also fine him and take his business license.

The same laws also prohibit you from "TAMPERING" with the emissions system. A few States even provide for the siezure of the vehicle if the emissions system has been tampered with.

All States can prohibit you from driving the vehicle on public roads if the emissions system has been tampered with, or fails to meet the polution standards.

They simply take your license plates, or refuse to issue plates for the vehicle. And if the vehicle is not "legal", that is not properly licensed, your insurance is null and void.

Lastly, it is a proven fact that you lose torque by removing the cats. The back-pressure provided by the cats is designed into the system by the engineers.

Food for thought, rangerj

Rangerj thank you for the info, i had no idea that such an extreme as vehicle seizure could take place just for removal of the cats eek! . I understand that it has been dyno proven to lose low end, but has it not also been proven to gain topend. What do you prefer to run on your sho cats or no cats. I do know this much about emissions laws in the state of Pa, that as of march the state has enacted a law which requires all vehicles to be equiped with their original emmissions equipment. Didn't mean to bad mouth that fellow either, I guess i should have just said if you want custom work with no cats that is not the place to go. Though I have to say I read about alot of shos having the high flow y no cats then having muffler shops put in resonators to **** the rasp. So where are these guys going? shrug

Hey and the SHOForum has helped me roll over 200k thumb Keep up the Great Work burnout

I don't know about the other people that have the SS catless y-pipe, but I have the SS catted y-pipe. As far as rasp is concerned it was horrible after the new y-pipe went in. Right now I'm running the y-pipe followed by a Dynomax (crap) resonator and a Magnaflow resonator after the gear box. With this setup pretty much all the rasp is gone, and I love the way it sounds. The other guys probably went to a shop that A) either doesn't care about the setup or B) doesn't know about the emission laws (doubtful). I don't know but maybe they told them it wasn't a street car too, but then how did they drive it there?

Mikey,

I'm still running with my OEM exaust system. When that goes I'll go with a Borla "Cats-back" system.

The States are under a lot of pressure from the Feds to reduce the amount of air polution. The States do not want to lose federal funding, for things like high-way projects. The States are becoming more aggressive, doing more testing, and issuing more fines.

I know New York and California have siezed cars for tampering and polution violations. Other States have impounded cars and pulled the license plates. The owners are required to pay a fine, the towing costs, impound lot storage fees, and have to get temporary plates to get the vehicle to a mechanic.

Once the car is fixed it has to pass inspection in order to get license plates. Very often the car is not worth the costs, so the owner abandons the car and the State or city sells it for scrap. The owner still has to pay the fine, towing, and storage fees.

This pollution stuff is getting more serious by the minute. You and I do not have the lobbying power of the trucking industry, or the buses, or the railroads, so guesse who gets their buts kicked?

It is federal law that all vehicles that are licensed for public road use have all of their OEM, or EPA approved, emissions components. The States are being forced to insure compliance, under threat of losing Federal funds. Your government at work for YOU. rangerj
