P1193 Fault Code

Getting a "P1193 Manufacturer Control Fuel Air Metering" using an Cctron OBD II AutoScanner. Searched this one but only found the P1193 and a different type of fault. Tried clearing it but it comes back after a few starts. Truck has sat for a long time and I did not have any codes until I recharged the battery. Only thing not stock on the truck is the radio but I believe the factory amp is still hooked up(pertaining to one of Mike at ECR's old post from way back). Thanks in advance if you can help. Mike

Registry
That code is: Oxygen Sensor Heater Circuit Open Downstream.

Any code that has a 1 after the P, instead of a 0 is a LR enhanced code.

EDIT: Here are LR specific codes: http://www.obd-codes.com/trouble_codes/landrover/

Cool, thanks PL and David. I was thrown off by my scan tool saying "P1193 Manufacturer Control Fuel Air Metering".

Argh. Replaced all for sensors and still getting P1193 error. One of the downstream connectors had some corrosion which I've vigorously cleaned. Any other ideas on what could be wrong?
