This is another pick for buying O2 Simulator. They have been testing and fully working on 2002-2003 5thgen Maximas. Should also work on 2004-2008 6thgen Maximas every bit well.

The iO2 was originally developed as tool to aid in the diagnosis of catalytic converter and oxygen sensor fault codes.Nosotros believe this is the most intelligent oxygen sensor simulator available, that's why we named information technology the iO2. The iO2 uses the vehicles live oxygen sensor signal to emulate and output a signal that closely resembles that of  a good  functioning goad.

The want to simulate an o2 sensor begins with the desire to remove the catalytic converters to permit free'er exhaust period. The problem is, the rear o2 monitors the frazzle content and the PCM can determine if the catalyst if performing or not. If the catalyst is removed, the PCM normally starts reporting P0420,p0430 faults for catalyst efficiency.

Simulation approaches in our inquiry showed ii bones idea'south, an electronic and a frazzle spacer approach (defoulers)

Electronic Simulators

555

Let's start with electronic, the 555 timer. Adult years agone the 555 timer was and still is the electronics hobbyist dream.The 555 timer was setup in such a style to simply output 450 mv to continue the PCM thinking the rear o2 was present.
However as PCM'due south grew in software function, tests were added to check if the rear o2 was really able to produce a voltage range of 0-one volt.Of course, this made the original 555 design obsolete, so the output of the 555 was changed to pulse from 0-1 volt at a fixed or even adjustable rate, this is the most electric current utilize of the 555 that nosotros know of.
This does piece of work for older technology, all the same it is hit or miss or will non piece of work for newer PCM's. It is a unreliable approach that will more than than likely lead to an catalyst efficiency error at some point.

The resistor capacitor set…. cap

An very common electronic filter excursion, but does information technology work?
Most equally well as the 555, yep and no, its in one case again hitting or miss dependent on the vehicle. It will pass the PCM's test for o2 sensor action, but similar the 555 timer volition, merely when it comes time to examination for catalyst efficiency (p0420,p0430) that's when they fall short.

Defoulers….

The direct approach, this seems to be very popular perhaps      because electronic approaches haven't been very reliable, and its  inexpensive. Do they work? once once again yes, and no. First they are far  from from stealthy, secondly they require routine maintenance.

They are not a guarantee for every vehicle, difficult to go just right  and crave cleaning from time to fourth dimension

At any rate, we just wanted to provide some insight based on our inquiry.

The io2 IS dissimilar.

The io2 itself, is actually a programmed device that reads an actual o2 sensor voltage, so cleans information technology upwardly.
The software within the io2 will forcefulness the output to act as though a catalytic converter is nowadays in the exhaust. So the PCM will see the point, pass the o2 function test and when it comes time for the dreaded p0420,p0430 the software takes care of that also.

scantool2The io2 during testing. The io2 was installed on a 2007 Chrysler product to field test the software. This test vehicle was driven in excess of 850 km's in all driving conditions, with no P0420 or catalyst efficiency codes generated.
the io2 was installed on bank1, input was taken from the bank1 main O2, the rear o2 sense wire was cutting and spliced to the io2 output.

Question and Answers

Question; What about another devices on the market for simulating o2 sensors?

Reply; Many devices currently on the market are based on a 555 timer, or a simple low pass filter circuit. Yeah they do work, sometimes, sometimes they don't, they are hitting or miss. The iO2 is a programmed microcontroller with software that creates the simulated output voltage, nosotros feel the most reliable arroyo.

Question; How many iO2's volition I need? some devices can be wired to 2 o2 sensors at the same time.

Answer; yous will need as many io2'due south as you have rear oxygen sensors (delight see our support page). You cannot reliably  employ a unmarried simulator for 2 rear o2 sensors, eventually the engine figurer on many vehicles will attempt to examination the role of the rear o2 sensors, it may non test each 1 at the same time, unlike other simulators,the io2'southward software is designed to recognize these tests,then simply put, this will not and cannot work.

Question; Will the iO2 work on my "whatever" vehicle?

Answer, YES! every bit long equally yous are using a low band O2 sensor as the input (every vehicle uses a low band for the rear O2 sensor) and the output is simulating a depression band O2. This includes all vehicles, even Chrysler,Jeep and Dodge products.
