Ok, i have a 99 Dakota RT and P0152 keeps comeing up which i know means HO2S Circuit High Voltage Bank 2 Sensor 1. I have heard that it may have to do with the heater circuit for the sensor but i dont have my repair manual where im at and i have no idea where to start. I have cheked my fuses and there all good and i have even replaced the o2 sensor and it still comes up. The truck does run really bad at times also. Can someone please shed some light on my situation.

 

When you changed the o2 sensor did you reset the computer ? If not I would try reseting the computer anf see what happens .

 

Yes i reset the computer.

 

did you use oem replacement or universal o2 sensors ? if used universals check the wiring and make sure the wires are making a good connection.

 

If im not mistakeing it was oem.. and when i pluged it in they clicked together and everything lined up the way it was suppsed to from what it looked like.

 

ok i was just wondering cause I just replaced mine with the universal ones and wiring them was a pain in the a$$ being I had to splice the connector on to it . im asking one of my buddies right now what he would suggest for you to do.

 

Oh okay well thanks alot man.

 

ok did you replace all of the sensors or just the one.

 

just that one and its not the only time ive done it. this is twice in like two months i replaced it.

 

I know this is going to be expensive , being I just did it but I would replace all 4 of them at the same time , also was there any damage to the actual sniffer part like any dents in it when you replaced it ( on the old one ) and is there a rattle in youre exauhst ?
