im running no cats, and i believe he said one was a bad map sensor (maf sensor?)

please help idk what these are

1 OBD-II Trouble Code: P0136 Oxygen O2 Sensor Circuit Low Voltage (Bank1, Sensor2)
2 OBD-II Trouble Code: P0141 Oxygen O2 Sensor Heater Circuit Malfunction (Bank1, Sensor2)
3 OBD-II Trouble Code: P0100 Mass Air Flow (MAF) Circuit Malfunction
4 2001 Mitsubishi Eclipse GT failed inspection due to DTC 1= P1400 Manufacturer specific code. What is that? - Yahoo! Answers

These links should help you understand. You need to run a cat or expect these codes. Dsmlink can bypass this but if emmissions is a need for you then fix your sytem. Get new o2s and cat. Wouldnt hurt to get a maf or map sensor as well.

All of these codes are cat-related?

Yes, well sort of. Many of them are actually o2 sensor codes, but you are getting these because of your lack of cats. Either put cats back in the system and replace the o2 sensors that are reporting codes, or get used to seeing your CEL.

You can't remove the cat and expect everything to be fine.

Well I'm not stupid- the guy who sold me the car had removed the cats and I'm new to aftermarket exhausts so I'm not entirely sure what to do about these codes. Did some more research and found these:

o2 sensor bypassing:

Opinions on these DIY fixes?

Make the DIY resistor/ o2 simulator box to deal with the code for the cat and rear o2 sensor beings bad. Cleaning your MAF isnt going to help with the other code. It is a circuit malfunction so the MAF is probably bad or some wiring problems somewhere . I would find a MAF in the classifieds and replace it.

 

[jpmxrider489]

Ill be selling a maf here shortly maybe in a month. Im not sure if the o2 sensor delete will let you pass emissions. I would assume not. I would just make your emissions work. Get a new cat and sensors and see what happens.

Definately be interested in the maf, please don't forget to pm me as soon as it goes on the market
