Help: Emissions NOT READY status!!!
Hello all,

anyone have issues with their PJ showing NOT READY on the 4 emissions sensors........

EVAP System
O2 Sensor
Heated O2

Pretty sure it's in the tune since JDM turns off the O2 with the high flow cats......

Anyone else have this problem?

Has the battery been disconnected? If so, you may just need to drive it for about 20 miles.

Emissions NOT READY
yes, I had the same problem, would not pass emissions. Had to Take it to Hennessey to due the tune to pass the emissions. Lets see how it does this year.

Anyone have any answers?? Mine is the Super Shaker version.

Hennessy should have checked to see if your "Supershaker Tune" ,which probably has the PJ Supershaker 3.6 SC pulley, has the CATS turned off in your 'Supershaker Tune". The 4 CATS need to be "turned on" or operating to avoid a "Not Ready" code. Hopefully, after turning the CATS back on, a FORD "Drive Cycle: should allow the "Not Ready" code to be cleared .

so how does one "turn on" the 4 O2 sensors? Is it the just the custom tune? So I need to get a custom tune from Brenspeed or someone else who knows these cars?

Emissions NOT READY
well, its inspection time, I am guessing they turned everything on to pass and then reverted to the old tune. I cant pass inspection, so I need to see if they have a permanent answer to this issue, as I dont want to pay $840+ each year to get my registration renewed.....Guess I can go back to Brenspeed, spend that money there instead of my watts link/torque arm. Any one knwo anyone in Houston that does good custum tunes? I am trying Peitz if I cannot get Hennessey to help out.

Michael, I sent to a detailed email about getting the correct Brenspeed tune for your PJ. Do not waste any more money on local tuners. Brenspeed can get it all done my email. etc. Brenspeed has a Texas location in Cedar Hill, south of Dallas but it can all be done via email.

I talked to Doug and we went thru the motions of getting an SCT tuner. Its on it way. They were hesitate to use your info but eventually had to as the PCM sticker was not there and the fuel pump booster was not in the trunk.

The tuner is on its way, thank you. Oh, by the way, the Brenspeed in Texas was closed in 2016. I wish it were still there as I would make the trip to have them go over the car and do some things.

emissions passed after using SCT Tuner from Brenspeed.
well, after I switched the tunes on the car to the one brenspeed sent me, the car passed easily after replacing the gas cap and doing a brief run cycle...

Anyone else with the same issues, I recommend Brenspeed.

Good News Michael. Brenspeed has been a great source for me.
