Have a 2003 land rover discovery have service light code p1451 how can I fix it have to pass emissions ? Please help try to reset but as soon as I reset the code comes back and service light goes back on...

Four digit codes are brand specific. For a Range Rover product, code 1451 involves the canister purge or vent circuit. This is the system that the computer uses to vent gas tank fumes to the vapor canister. You will need to research this in depth for Range Rover models to get the test procedures. The warning light will stay on until the problem is fixed.

P1451---Evap Control System Canister Vent Solenoid
Circuit Malfunction

When vent solenoid is open it will indicate 0% duty cycle &
Voltage approx equal to battery voltage
When commanded closed will equal 100% duty cycle
and drop to 4 volts

With the factory diagnostic manauls & pro scan software,
you can do a lot of testing of things

Appears more wiring than the solenoid,could be wrong

Have to follow trouble charts

The code came up p-0743 how do i fix this

You replaced the O2 sensor and the other codes popped up ?
I would clear the codes and see how many return. Often times the problem is not the sensor but rather something in the engine performance.
