And where can I find correct values? Checked O2 sensor. Hot engine idle 0.1V. And 3000rpm 0.9V. Found in autodata that it must be 0-1V. I will check resistance of other sensor, bacause that I can find in autodata. Nothing more.
Is there any kia orientaden obd software like vag com for vw?
Oh sorry. Totally forgot that: 2000y 2l petrol 16 valves 128hp 5speed manual 150 000 km on the clock. Germany or Netherlands.
I think it drives the same. Well light is on for a long time now and I drive car just occasionally. Once for 2weeks. I checked sensors resistance. I found that throtle position sensor is bad. Well at least I think it is because according to autodata TP sensor resistance should be 800-1000 ohms when closed and it show 1700ohms. Strangely enough MIL does not come instantly, only after 10-20km.
Hmmm! you are running PETROL, must be in the colonies!! and you have OBDII?
What was the original market for that vehicle??
Provided the back pressure test verified the CATs as OK (taken at front O2 bung,<3psi @2500rpm)
time to connect a LIVE DATA SCANNER.
COLD engine, (KOEO)
AIT (air temp)and ECT(coolant temp) must be with in 2% of ambient temperature
TPS, 0% at stop and rise smooth and steady as throttle is advanced
MAF, 0% with no air flow
Battery, 12.6vdc, fully charged.
ECT, must start to rise and attain and hold 180* at idle and 2000rpm
CL (ECU) must maintain at idle and 2000rpm
MAF, small reading at idle and rise steadily as throttle advances.
O2, (B1S1, precat), must start actively switching with no lean/rich bias...
LTFT, (long term fuel trim), close to 0%, +/-2 is allowable, if more, time to investigate fuel delivery/illegal air
Vacuum, at unregulated manifold port, 19-21”hg..with a dead steady needle, investigate jitter or bounce.
Well everything seems good except O2 and TPS. What should be value for tps at idle? Mine showed 12%
O2 (B1S1) - 0.11-12V, not much actively switching. Just by 0.1V This one is definetely bad. Is there only one O2 sensor?
Edit: I checked O2 sensor on other car and now I can see what you meant by "actively switching". O2 sensor is definitely dead. Thanks Philip
