Anyone had these fault codes?

My diagnostic light came on and the following fault codes were read.....

1. 17511 - O2 Sensor Heater Circ. Bank 1 - sensor output too low

2. 17524- O2 Sensor Heater Circ. Bank 1 - sensor 1 open

3. 18010 - Power supply (B+) Terminal 30 low voltage


I erased the codes and the light has not come back on (12 miles)

Anyone know what the problem is?

My guess is something to do with Lambda sensor. The car is running spot on.

Prehaps i should have searched first???

18010 is because I reset the ECU by disconnecting the battery.

And the other 2 are Lambda (pre-cat related)

The codes have been cleared and not come back. Could this mean a dodgy connection to the Lambda?

Its difficult unless you now how long the codes have been there. I would keep checking them. If they come back, I would change the sensor.

The phrase "open" means there is an open connection and this would point, initially to the connections but if they look ok, I would change the sensor. (definitely pre-Cat)
