Error p2626

[AA95101]

Hello,

I used to use my JB4 with fuel wires without issue but removed the tuner for the recall update.
I just reinstalled my tuner and I’m getting an error code p2626.
I disconnected the wires and the error goes away.
What could be causing this?
thank you

Verify fuel wire connections.

I tried uninstalling the fuel wires and turning off the fuel control in the app settings. error still stays

Did you clear and still came back? Do you have the plug n play fuel wires sonyou don’t have to pierce your o2 sensor.

I cleared the code and it still comes back, I have the plug and play setup

thank you

Are you sure you hooked your JB4 correctly? It is possible to have the connections back-assed.

I installed this setup previously without issues. based on the lengths they shouldn’t be able to install incorrectly

I may need to open it and check for continuity
When I installed it I also updated the firmware to v22 before driving it. Could this update be causing this?

anyway to downgrade the firmware to test?
thank you

Also on a side note I originally had the ewg connectors installed but didn’t have the time to install them for the install, I have the ewg turned off in the app to allow for this.

I doubt the firmware is causing the issue. I’ve been running the update for weeks with no issues and haven’t heard anyone else complaining.

I disconnected and turned off the fuel control and the error is persisting. I believe this could be caused by an issue in the tmap and map sensors. I’ll check for continuity this week, could anything else cause this?

is there anyway to reset the setting back to factory? Or can someone post their factory settings?

If I post a log would that help narrow down the issue?

thank you for all your help in this issue. It seems as though I’m the only one experiencing this issue

Also I uninstalled the tuner last night and the error disappeared, this issue is somewhere in the tuner

Just installed my JB4 with the pnp adapters tonight and getting the same issue. Did you ever figure out a solution or anything?

i found out one of the wires had disconnected from the fuel control connectors. I ended up getting a new connector and repining it. I would double check all the wires are firmly in place and your not seeing any shorts. good luck
