O2 Sensor, Bank 1 Sensor 2

[BigBoss]

Hey Lads,

Was driving home tonight when the check engine light came on, so I check the codes via my iPad and before I was home I had found out it was the code "p013A" which means "O2 Sensor Slow Response - Rich to Lean Bank 1 Sensor 2". Tomorrow I will be off to Holden to pick up some new ones just wanted to know which bank is bank 1? Is that the one just near the cats?

Cheers

BB

Bank 1 = driver's side of the car
Bank 2 = front passenger's side of the car.

Cheers Mate, got em sorted, I replaced bank 1 sensor 2 and bank 2 sensor 2. two genuine sensors from Holden cost $250, A bit of a rip but needed them today.

Digging up an old thread cause I got (had) this code. Engine runs well with normal fuel economy and I've cleared the codes around 750km ago, hasn't returned. Yall reckon it's worth replacing the sensor or just leaving it seeing as the code hasn't returned?

How many kms?

172,000km total. Done about 1200km since the code popped up on Saturday. I do have an aftermarket catback but I've done 50,000km since that was swapped over.

Might be time to replace them.
