Engine swap Emissions ?

Mark m. · Feb 7, 2012

My is rig is a 89 toyota 4x4 truck I took out the 3.0 and installed a 3.4 toyota engine. When I go to get it tested are they going to test to the the 1997 3.4 standard or the 1989 3.0 ?
I do have the obdII plug installed in the new harness. I have one code for a speed sensor but I had the same code with the 3.0

my understanding of the rule is it is tested under the licensed year/make of the vehicle.

so lets say you had stuffed a chevy v8 in there or 4.3 who cares...

it would have to pass the standards for your year and make of vehicle...

If I remeber right from when I used to DD my zuk you have to pass for the engine. With my zuk I just never told them what engine was in it and they never asked or looked.

The 96 16v always passed the 87 standards on the sniffer with flying colors.:cheer:

Well thats one for each. I guess I should just contact the emissions place and ask them.

As long as your 12v accesorie plug works your fine. They will have no reason to open the hood. Assuming you have the 3.4 working correctly and have most smog equipment on there. Your going to run cleaner than a 3.0 anyway. Now if they pop the hood and the person has half a clue. Then this changes things. You will have to pass under the year of the engine. In this case you need to have the obdII system working propely or that rig will never pass WA emissions. If they can't plug it in and see all your radius monitors working, your fawked.

Well the supercharger is not going to fit under the hood. All emissions are hooked up on the 3.4 but I'm getting a code for the speed senser. I have no idea what that is.
I guess I can just play dumb and see what happens.

Could it be for ABS?

That things gonna rip Mark.:011:

I think it may have something to do with cruise control.

exactly what code is it?

I have never had a newer rig to take in for testing so I am not sure if they 'PLUG IN" or not...... that being said all the older OBD1 rigs get the sniffer up the tail pipe with the bag on the hood (RPM test) and as long as you have the hood shut (evan with a hood scoop) they should not care. But you can run into problems if you have more cylinders than the model came with, can through the RPM reading off.
Looks like it should run

I forget the # I'll have to check again. Pretty sure it said speed sensor though.

Yes it does

As it was explained to me emission requirements are based off the year of the vehicle--not whats under the hood.

And for swapping motors it must be the same year model or newer.

I am not sure what they did for OBD I when a ses lamp was on but OBD II vehicles you would fail on the IM flag(ses lamp).

mine flashes this code occasionally also, I believe it is a sensor in the dash/ speedo. I usually just pull the efi fuse for 5 sec. and I am good for 6 mon.

What are these emissions tests that you speak of?

:flipoff:

If I'm reading the laws correctly, it states that if a newer motor is swapped in, the emissions system of the chassis year must be used.

http://www.epa.gov/compliance/resources/policies/civil/caa/mobile/engswitch.pdf

It should be noted that while EPA's policy allows engine switches as long as the resulting vehicle matches exactly to anv certified configuration of the same or newer model year as the chassis, there are some substantial practical limitations to performing such a replacement. Vehicle chassis and engine designs of one vehicle manufacturer are very distinct from those of another, such that it is generally not possible to put an engine into a chassis of a different manufacturer and have it match up to a certified configuration. Therefore, practical considerations will generally limit engine switches to installation of another engine which was certified to be used in that same make and model (or a "twin" of that make and model, e.g., Pontiac Grand Am and Oldsmobile Calais). In addition, converting a vehicle into a
different certified configuration is likely to be very difficult, and the cost may prove prohibitive.

Does the state go off what the EPA says? Or do they do their own thing?

Zoediak · Feb 8, 2012

as it was stated to me, at the emissions place when all this started years ago (and I stated earier) the emissions goes by the year/make of the vehicle.

If I took my 2001 chevy blazer and put in an older hotrod engine, that engine must pass the 2001 emission standards for the vehicle...

now, with that said...

if you go the other way, and swap in a newer motor (which has higher emission standards) into an older vehicle, you will still have to pass the emiision standards of the vehicle.

the biggest issue is when more cylinders are added (equals more emissions) or different engines swapped into a veichle, like a chevy into a toyota/jeep..

just get your code fixed/cleared, take it down, pay the money, get it tested..... if you fail, it will say why and you get a free retest...
