2001 sportage stalling/codes

[natalieRN]

HELP!!!

My sportage started stalling out on my 2 weeks ago. We have changed the fuel pump, filter and plugs. The coils are testing good. It runs but starts to bog out like it is not getting fuel. We changed the timing belt on it yesterday. Today was still hard to start and left me at Advanced where I had the codes run and these are what came up-
P1115
P1624
P0135
P0141
P0134

We have just disconnected the bettery to try to reset the codes- Do I have to change the O2 sensor? Is it the TCM? HELP?

Thanks!!!

P0134 Oxygen Sensor Circuit No Activity detected - Bank 1 Sensor 1.
P0135 Oxygen Sensor Heater Circuit Malfunction - Bank 1 Sensor 1.
P0141 Oxygen Sensor Heater Circuit Malfunction - Bank 1 Sensor 2.
P1115 Engine Coolant Temperature Signal from ECM to TCM.
P1624 MIL Request Signal from TCM to ECM.

I'd be surprised all of that would come on a sudden, specially both O2 sensors : I think the voltage supply to the O2 sensors is dead...I'm even surprised you do not have P0140... may be a blown fuse....
I do not know if you have THIS (750k)
(this is when KIA had a free information site)
follow the path on page 25-1 and page 25-5 for the O2 sensors. Make sure supply, fuses and grounds are OK...bad grounds are a curse on this Sportage.

I got it to Advance. The computer is reading O2 sensors. Bought new ones. Thanks for the diagram. Now the hold light and the check engine light are on. Gonna change the O2 sensors and check the grounds. Why is the hold light on?

Thanks for the input.

..YOu mean is stays ON even if you switch the shifter button ?
If it flashes, it means it senses a transmisison problem....but this problem can be induced by other factors. Clear the other problems first...
