PO-139 I had that sensor change 3 weeks ago and the check engine light came on again this morning.Thanks


Probably replaced a good sensor. This codes could be from a bad sensor, a vacuum leak, or an exhaust leak before the sensor.

In order to get the light out you will have to replace the rear O2 sensor.

Is the PCM the issue?


The P0140 code is caused by or is affected by the P0141 code. Fix the P0141 code first before worring about the P0140.
It is good you had the connections cleaned as oil contamination will cause a problem with the O2 system.
The "automotive electrician" should have performed a continuity test from the O2 sensor heater fuse to the PCM connector were the heater is grounded. The resistance value should be 35ohms. If the value is too high, the PCM will set the P0141 code. I would suspect you have an open circuit in either high or low side of the O2 sensor heater circuit.
Good luck.

I took my Town&Country in to a local shop to have them scan the codes as my engine light is always on. I received 2 codes: P0140 1/2 O2 SENSOR and P0141 1/2 O2 SENSOR. Would the 2 O2 SENSORs be...


Codes alone don't tell you what to replace. I assume you mean catalytic converter. The converter should last the 10 to 15 years if nothing damages it. You now need to continue on and see why the o2 codes were set. The local shop should be able to take care of it. Just be there and be part of the process, so you know what work to approve. Don't take the vehicle back untill you go for a road test and see the codes are gone ,with the scanner on the veh. Take the scanner on the road trip

My car indicates check engine sigh with following two codes 1: p0139 2: p0140


Hi Garcha,

Both codes relate to O2 Sensor # 2

Code P0139: O2 Sensor Circuit Slow Response - Bank 1, Sensor 2
Code P0140: O2 Sensor Circuit No Activity Detected - Bank 1, Sensor 2

A faulty O2 sensor will mean incorrect signals will be sent to the EFI computer, causing erratic engine running.

P0139 code for a 2003 hyundai elantra. What is this code?


Hi the code P0139 is Bank 1 sensor 2 lambda sensor fault ,possible wiring or sensor fault even if you replace the sensor you need to have the MIL lamp turned off by a Diagnostic machine,it is possible you have another fault such as poor Catalytic converter efficency giving the same fault code ,Would recomend you get the car checked and read the "live" data as the car see`s it to make an accurate diagnosis and cure

One thing to check is the fuel pressure regulator.
If the diaphram is leaking it will cause gas to be pulled into the vacuum system causing lots of white smoke and extreme rough running.
