Peugeot 307SW 1.6-2004 DTC P0141

[Msmax]

Update1:
After driving for a few days the engine light went off by it self.
It seems that DTC clearing is better done with standard OBD2 interfaces like ELM327 then with PPS2000.
Problem solved.

Update:
Any one can check for me what the heater resistance is for the O2 sensor with blue connector?
The used new one is around 10 Ohms. The old one was 14K, definately defect.


Guys,

Have a very strange problem.

Engine light was on, checked with PPS2000 and found P0140 and P0141, heater circuit of O2 sensor after CAT.
Measured the sensor and it measured around 14K.

I replaced the sensor by a know good one (~10Ohms) but I can not reset the DTC.
Checked wiring and voltage levels, all OK.

Some thing wrong with my PSA Interface?
Tried with 2 different PSA interfaces.

Your help is appreciated.
