PO141 check engine light keeps coming on

Try swapping the front sensors and see if the code moves to the other side. Heated 02 sensors can short the heater circuit into oxygen sense side and it gets confusing. If it doesn't travel with the sensor you'll probably end up having to pin out the sensor wiring. I hope this helps, take care. If you have more questions for me use testimonial. Thanks

I assume that you performed a Clear Codes after doing this to reset the check engine light and then retested......otherwise the codes will remain until you do so.

what usually is done is the codes are cleared and the car is driven then if the check engine light comes on or a week later no light comes on have the pcm rechecked for codes as sometimes you can get what is false codes,codes that momentarily set but are not actually a problem.

You should have 4 O2 sensors and it sounds to me like the wrong one was replaced. Bank 1 Sensor 2.

I think it,s your check engine light. but if theres still a problem check to see if your battery is chargeing you might need a new battery . let me know

CODE PO178 FLEXIBLE FUEL SENSOR

The check engine light bulb in the instrument cluster is probably burned out

po141, may be a bad o2 sensor, rear sensor after converter. the po 141 is low voltage to tps, try replacing the oyxgen sensor first and then reset the codes and drive if the po141 comes back then replace the tps,

how do i fix or reset this fault
Engine system fault,park brake faultengine system fault, park brake fault & dsc not avilable

according to the manual i have... it has three.... one in the exhaust manifold.... and two in the exhaust pipe..... slightly vauge on the exact location of the last two sensors... but looks like it is after the catylitic converter.
