How many would you need in total? I have a cat delete with mid x-pipes and a magnaflow competition exhaust.

  • Two of the Prosport Mini Cat 02 Sensor CEL Fix will be required. One for each rear O2 sensor. These should never be installed in the front (upstream) O2 sensors as this can cause engine damage.

I triggered a check engine light due to my exhaust setup. I installed bbk long tube headers, O/r x-pipe on my 2013 mustang gt. The code was giving by my sct X4 was P0155 O2 Sensor Heater Circuit Malfunction. Do these trick the car to turn the Cel? How many of those do I need. Should it be installed in the front or rear O2 Sensors. Is it just a tread between the O2 sensor and the port on the exhaust? Should it be facing upward or downward? Thanks

  • P0155 would be caused by an electrical issue. Typically we see a damaged O2 sensor, or O2 sensor wiring. This code indicates the issue is on the front O2 sensor on the passenger side. The Prosport Mini Cat 02 Sensor CEL Fix is designed for the Rear O2 sensors and should never be installed on a front O2 sensor. These are designed to help eliminate P0420 and P0430 catalyst efficiency codes, and would have no effect on the P0155 code.

Do these come in a pair? Or are they sold separately?

  • This will include 1 Mini Cat O2 sensor fix unit.

I do not currently have bungs for o2 sensors on my exhaust. If I purchase this item I will need to weld bungs in, but where would I weld the bungs in at? Thank!

  • The Prosport Mini Cat 02 Sensor CEL Fix is designed to thread into the OE location for the rear O2 sensors. Typically you will find these after where the cat would be, near the crossover (X or H pipe) in a straight section of the exhaust.

When using this product, will there still be a need to run an 02 harness extender with long tube headers?

  • With doing long tube headers you would still need the o2 extension harness yes.

    05 Mustang GT exhaust set up

    My set up is a pypes off-road x pipe to flow master 40 delta flows. Two of my 3 mini cats worked, but the driver side one was reading slowly so it still caused a check engine light to come on. Their purpose is to prevent the light, but I got one anyways. That’s why I gave it 3 stars. If they all worked then it would be 5 stars.

    It really works

    Houston Tx. I could not pass inspection, mbrp catted downpipe. 2.3 ecoboost. Cobb stage whichever... or stock tune.. Well guess what ... Installed in less than 20 minutes, it took longer to jack the car up, than to install. All "ready" on all O2 sensors in less than 50 miles, this absolutely works...

    Mini Cat 02 Sensor CEL Fix - 45 Degree

    Whenever I removed my catalytic converter for a better off-road ride the pesky check engine light could set off which was both annoying and distracting. With this Sensor CEL Fix, It doesn’t happen anymore.
