This right here. Is there anyway we can wire in resistors to fool the ecu into thinking it has the air pump plugged? Im getting my Cobb AP within the next week and I'll be masking emissions to pass NY state inspection and I also wanna ditch the air pump. But from my understanding of reading thru this thread it still won't clear readiness unless the air pump is physically plugged in? Even if I mask the DTC's with the AP?

There is at least one or 2 people that report it working with a mazdamaniac tune. In the same thread i posted that teamrx8 reposted a list of codes mm used. Thats what I'm running right now and hope it works if not ill start trying to fool
It.

Cool. Looking forward to your updates on that. I kinda just wanna delete the air pump completely and not have to worry about keeping it around for inspection.

every year, same story.... plug in air pump... drive for a couple days to week with it.... go do inspection.

Here's what I know: In most areas 2 tests can fail. With the air pump disconnected I do not believe the test is even able to run so it stays in a pending state.

At least with it connected it'll eventually fail or pass -- mine normally fails because it runs a couple milliseconds more than it should -- at least that's what the readiness test reports.

In any event, the test eventually fails or passes with the air pump connected. So long as no other tests are failing you'll still pass the OBD2 inspection test.

If the readiness test is actually reading the O2 level of the forward O2 sensor during the cold start cycle then it doesn't matter if the fan is merely connected, the test will fail without the fan blowing into the manifold.

Has anyone simply tried jumping the pins and leaving them jumped? Continuity seems like a much more likely form of measurement than resistance or load.

You will get a rich condition at start-up and the test still fails, I have tried almost every option. I ended up just leaving my pump installed and stopped messing with it. It hurts nothing so I just left it.

Thats what i was proposing, use a resistor to jump the 2 connectors.

A lean voltage when the fan is on could also be faked with a relay and a few resistors. So it gets a lean voltage when the pump is on. Then when the pump goes off it relays back to the o2 sensor output.

at least the readiness test completes....

or just let it fail...

The monitor looks at more than just pump activity Shell, It will not become active if the following

Open circuit connecting pump
Pump start up within 5ms of starting the car
Rich to lean condition detected

Which is why I just left it in, especially with the headache of my new exhaust no way am I swamping manifolds every year for this so I just leave it in and running.

for 2001+ vehicles the EPA allows 1 test to not be set i.e. pending. There is no pass/fail requirement for the one test. Pending is fine. I have personally witnessed/been involved with RX8s not having an air pump and reaching the 1 test pending phase and passing the state OBD2 test using the Cobb system.

Must have been nice. 1200 miles 44 drive cycles and I could never get the catalyst and air pump monitor to turn on.

6/8 is no bueno.

Why is your catalyst not setting?

No idea, maybe 410 related.

You have a problem somewhere. With good sensors & wiring in place and the correct codes blocked the catalyst test will set.

Its a rear o2 code, I have a brand new upstream o2.

I am not sure if its cat related or not TBH, I am straightpiped, never actually looked around into it but its the only code I have so I am also not worried about it.

Then you must not have the proper codes blocked as previously discussed.

There's not anything nice, or lucky, or magical about this. Do it right and your car will pass a non-visual OBD2 test without an air pump installed.

Yeah, that's fine by me. I have no experience trying to pass with any pending readiness results. I always get them to a final "state" before going in.

What team said.

Thanks guys this is what I was looking for. I believe NY state allows you to pass with one readiness monitor not setting.

I saw the list earlier in the thread of all blocked emission codes MM blocks in his tunes, so long as I block everything else and all my readiness monitors set I will mask the air pump DTC and delete it completely and whether it sets readiness or not I believe I can still pass as long as all my other monitors ready.

sounds legit

I pass my OBD2 test every year without the air pump. I just have a lot of codes disabled in the cobb.

there is a lot of misleading info here, hopefully people will read the thread through fully.

I just deleted most on my earlier posts for clean up purposes.

Bumping this back up. I have a problem with my readiness monitor setting for the air pump/secondary air.

I created a map specifically to pass inspection (I have all CELs blocked on ATR). Been driving for probably about a month with them all blocked and Secondary air just doesnt seem to ready itself.

I have the air pump deleted and the solenoid is deleted and blocked off as well. Any one have a solution to this beside plugging the air pump back in.

I no longer have a stock air pump.

What else is not set for readiness then?

I have to double check my hand scanner again but I believe it was either evap or A/C monitor that was showing not ready. I'll check in the AM and update.

Evap should have already set in a month too. There may be another issue somewhere. Some model years may respond diffeent than others too. Might be best to state what it is for comparison purposes.
