CEL code help please

Hi guys,

I have the P0132 code which I believe is the O2 Oxygen Sensor Circuit High Voltage (Bank1, Sensor1).

What exactly does that mean and what are the possible fixes?

FYI: I did replace the O2 sensor at 50k miles. Plus, I also have high flow cats (which i have a feeling might be causing the code but it didn't before.)

TIA

G

Have you had the Camshaft Position Sensor oil leak problem? Does your car have the pigtales fitted? Check for oil in harness

Cats should have no effect on the upstream O2 sensor.

Might have a bad sensor.

Pigtails??

And how would i go about checking for the oil? A while back I had checked for oil in the cam harness and it was all good there.

Thanks

See if oil is leaking at the cam sensors - pull the harness plugs & check. Look for oil at the O2 sensor connector.

These are pigtales.
