2001 Lincoln Navigator V8 All Wheel Drive Automatic 87000 miles
After a long period of time hearing something that sounded like a noisy pump of some kind, the back of the Navigator has dropped to the bottom of the shocks.
I no longer hear the sound.
I'm guessing the pump died and I'm hoping it is a reasonable repair.
I borrowed a code reader from my brother, but it only showed code P1131
" HEATED OXYGEN SENSOR (HO2S) MONITOR - HO2S LACK OF SWITCHING
Diagnostic Trouble Code Description Possible Causes
P1131 -Lack of HO2S-11 Switch, Indicates Lean When an HO2S sensor indicates lean at the end of a test, the system is trying to correct for an over-lean condition. The code is set when the fuel control system no longer detects switching for a calibrated amount of time. See Possible Causes for DTC P1130"
I'm also guessing that OBDII code P1131 is not related and will be another problem I have to fix.
Can you give me some idea of the parts that need to be replaced?
I've done a log of " backyard mechanicing", but mostly 20+ years ago.
