Are both my Lambda probes knackered?
I've got the following 2 x DTCs in the ecu:
P0135 - Powertrain 02 Sensor Heater Circuit (Bank 1 Sensor 1)
P0141 - Powertrain 02 Sensor Heater Circuit (Bank1 Sensor 2)
I know there are 2 x probes in the exhaust upstream and downstream of the cat.
Looking at this I'd say they were both knackered.
Anybody agree / disagree or willing to provide any kind of troubleshooting before I get the wallet out?
Cheers.
Rob.
