help please! 02 sensor question

[Hicomp]

hey guys just wondering what in gods name does this mean?

P2234 - Generic
Type Powertrain - Fuel and Air Metering and Auxiliary Emission Controls - ISO/SAE Controlled

Description
O2 Sensor Signal Circuit Shorted to Heater Circuit
Location Bank 2 Sensor 1

Notes
P2231-P2236, This diagnostic is for the sensors (both wide band and switching) that have a PWM controlled heater. If the heater shorts to the signal circuit, the control module can determine this since the signal circuit will be shorted high at the same frequency that the heaters are operating at.

Any help would be great, thank you!

sorry to hijack Hicomp but I have the error P2231 - O2 B1S1
so if anyone can tell me which O2 sensor that is... (passenger side front?)
thanks

Cylinder 1 is on RHS. So bank 1 should be RHS.

Should be front sensor.

Sounds like the same issue that the VS had. Replacing the sensor won't fix it, you will have to rewire the earth for the sensor back to the PCM, or cut the heater wire. I don't know which one it is on the VZ.

yeah u guys took too long too respond hahaha, replaced all four sensors and no more check engine trans light!! happy days.
i had that error code and 2 other sensors sending out some crap codes so thought might aswell replace all of them.
but thanks guys!

Good to hear its all good now.
I just changed my front ones but might change the after cat ones.
Just wondering how much did they cost you?
Cheers.
