ok so i pickd up n eg, put the motor in. got three CELS= 1, 41, 48

1.now the ecu is the p07- (vx) n i got a 4 wire oxygen sensor. that would throw the 41 and 1 correct? because its supposed to have a 5 wire o2 censor or a o2 sensor on the cat. now the 48, lean air Fuel?? would that be due to the o2 sensor.

2. i dont know what distributor i got on it but, its not lining up. what other distributors can i interchange...z6 distrib?

n 3. theres no temp sensor(the one that goes to the gauge) but im not gettin a CEL for that

any help appreciated.


no please

 

Fixing the O2 sensor wiring will likely eliminate all three CEL codes.

The engine has three temperature sensors:

(1) coolant temperature switch for the radiator fan

(2) coolant temperature sensor for the ECU

(3) coolant temperature sending unit for the gauge

Only a problem with (2) would throw a CEL code

coool coool. ya will picking up a p28 make me be able to run a 4 wire o2 sensor correct?


n what distrib to run?

 

outcoming of running a p28? can i pass smog in cali?

 

The P28 maps are for 240cc injectors...so wouldn't the motor run rich with it?

BTW, I have a '95 EX coupe with a crappy D15Z1 swapped in it. I also have the CEL 41, but it has a 4-wire instead of a 5-wire. But would the Ex main harness accept or read all 5-wires if it was used?

ya but does anyone think i can pass smog???? the harness i got was for the 4 wire o sensor.?? what ecu you running?

 

If you have a Z1, you need a P07 and the oem wideband O2 sensor. The P28 will only hurt you.

The Z1 and Z6 distributor is the same part and its the only distributor that will work for those motors.

Passing smog depends on so many possible maintenance variables that I cannot comment. Get all the correct parts together and do the regular maintenance.

 

the cars already wired for a 4 wire 02. engines running perfect besides 02 sensor codes....just wanna know if i could smog it then get it chipped??

anyone pass smog on this set up?

n the widean o2 sensor is 300 [freak] tha

 

p28 on d15z1 hellllp

 

ttt

 

P28 on a Z1 will run like crap.
the Z1's head/cylinder design is a lot different than the Z6.

Pick up a P07 and a five-wire O2 and enjoy the 40+ mpg it will pull. (keeping your foot out of it of course)

IF you really want to run a P28, then you'll need a P07 and 5-wire O2 for a few days to pass cali-emissions.
After that a highly tuned P28 should be able to run the Z1. But anything less than highly tuned and you will regret it. (poor mpg, poor power, possible engine damage, etc)
That engine is finicky and there is no real easy drop in solution with the tune. (the cali-spec P07 maps work fairly well, they can be pulled from PGMFI.org)
You'll need to pick a local tuner that's known and cross your fingers.

 

ohh so the p28/ n 4 wire wont pass cali emission. what about with a p07 fuel map? or whatever

 

last time I checked the cali emissions test checks the number on the side of the ECU... it has to match the engine, or fail.

 

I have a P07 in my EX with the Z1. Problem is I still have all the original EX "accessories" : including the IM, exh, main wiring harness, and O2 sensor. I did swap to Y7 190cc injectors, but I still have a CEL41. Thing is, if I got a 5-wire for this thing would the harness accept the O2 or be able to read the needed data sending from it? Is there a DIY for wiring from a 4 wire to a 5-wire? LOL I know it's usually the other way around.

These are contradictory statements.

So you're in CA. Well you're in big trouble then. You have to have the original engine for the car or else it automatically fails. If it's not the original engine, it has to be an approved replacement engine and you have to take it to a Ref station. The donor car has to be the same year or newer, and all the original smog equipment has to be used. The original ECU has to be used. It has to have the original intake, intake manifold, exhaust manifold, cat converter, O2 sensor, EGR, charcoal canister. Some of these parts can be replaced with 50 state legal CARB approved parts.

Chipped ECU is not smog legal in CA.

so what do i do? the harness i got came with the 4 wire? i didnt know the vx was a 5 wire. i got the p07. so what do i do spend 400 on the 5 wire and run it straiht to the ecu?

 

can i get a cat with a bung n get an o2 sensor would that work?

 

run the 5-wire O2

OR

find a P07-L01 or L02.
these are cali-spec VX ECUs that use four wire O2 sensors.
But they are few and far between.
You also will not get as good fuel mileage as with the 5-wire O2 and the 49-state spec P07.

 

runnin p28 on it 4 wire throwin a 1 any help?

 

ok dude check this out. For a VX you need a 5 wire o2 sensor, those are wideband sensors. IF you want to pass smog you'll need a 5 wire o2 sensor NOT a 4 wire. If you don't have a 5 wire plug try this link maybe it will help.

z1/z6 distributor is the same thing.

also verify you have a vx engine by the d15z1 stamped on the front of the block.

 

He's been told about 5 times now. Just let it drop.

im tryin to run a 4 wire. im gonna get a smog hook up just wanna get rid of the CEL

its been done b4, so it can be done.
