SOURCE: ODB-II Trouble Code of 1151
P1151-Lack of HO2S-21 Switch, Sensor Indicates Lean
A Heated Exhaust Oxygen (HO2S) sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time.
A code P1151 may mean that one or more of the following has happened:
Leaking/contaminated fuel injectors
Leaking fuel pressure regulator
Low fuel pressure or running out of fuel
Vapor recovery system

P1000 means a drive cycle has not completed, it will only clear itself
after driving the vehicle through certain driving conditions. If you
try to clear the code, it will reappear until you repeat the drive
cycle. I am not too familiar with what AE will show, but if you can
access Mode 6 data or the OBD Drive Cycle(These are two options from
the IDS at Ford), It may help to show what tests have either failed or
not completed. Heres what must be done to clear the P1000:
Note: The IAT PID must be between 10-38°C (50-100° F) during the OBD II drive cycle to enter into all the OBD II monitors. The FLI PID must be between 15% and 85% at all times.
Drive in stop-and-go traffic with at lease 4 idle periods (30 seconds each) while observing the status of the OBD II monitor on the scan tool. If the exhaust gas recirculation (EGR), heated oxygen sensor (HO2S), evaporative emission (EVAP), secondary air (AIR) (if applicable) or catalyst efficiency monitor have not completed, drive on the highway at a constant speed over 64 km/hr (40 mph) not to exceed 104 km/hr (65 mph) for up to 15 minutes. Heavy accelerations, sudden decelerations and wide open throttles are not recommended. If the scan tool sends out a three pulse beep at any time, the OBD II drive cycle has completed.
If there is only one certain component that hasn't completed its test, there are individual driving conditions to help those tests pass or fail if something is wrong.
