I am getting error code P0152:
2/1 sensor shorted to voltage oxygen sensor input voltage.
Translated (thanks to these forums) basically means "replace h20 sensor passenger side before converter"
Please correct me if I'm wrong as I am no mechanic.
Upon researching again through these forums I found out that NGK also known as NTK is the original OEM oxygen sensor, and seems to be most recommended.
I just give you a quick run down. (my previous exhaust was custom but it failed an out of province inspection) So i purchased a walker Catalytic Converter (with y pipe) Part 56092. Click to see image of my cat
That new exhaust runs down the passenger side to the tailpipe.
I am looking for the sensor that is between the cat and the motor.
I go to NGK website and they have pre cat left, and pre cat right. I assume mine was pre cat right reg club cab (even though mines technically a crew cab.) since my exhaust is on the passanger side.
The link to NGK/NTK H2O sensors for my truck
I do a few searchs on NGK 23135 (pre cat right).. and its seems this is compatible with my truck but just to double check i checked NGK 23137 (pre cat left) and this too is compatible with my truck.
Since I believe I only have 2 sensors
1 pre cat also known as upstream and,
1 post cat or downstream
which of these 2 are the correct OEM product? NGK 23137 or NGK 23135
They make these parts lists so confusing i swear..
I would prefer purchasing something cheaper but I have read oxygen sensor can be different amps ect. and overall I just want one that is reliable, and give me the best possible fuel millage.
