The Knock Sensor (KS) is mounted on the engine, above the alternator and used to sense engine detonation. The knock sensor is a frequency amplifier with the sensor designed to resonate at approximately the same frequency as the engine knock. This allows relatively large signals to be sent to the Electronic Control Assembly (ECA) without electrical amplification and with a relatively small sensor. The ECA uses this information to alter the ignition timing to optimize ignition timing while reducing the occurrence of spark detonation.
According to the 2004 Ford F-150 Owner Guide : With engine oil filter change : The 5.4 liter V8 takes ( 7 quarts )
54
54 mg per liter = 0.2 grams per US gallon.
It is 17 litres.
Code 54 is the Camshaft Sensor Circuit
this depends on the spark plug you use. If you use autolite spark plugs you will need to gap them to 54 thousandths.
code 54 means there is no signal from the pickup coil aka ( cam sensor ) to the pcm.
It means the primary crash sensor circuit has had a short to ground, possibly an activated crash sensor due to a crash detected, and then the issue has gone away, in other words, it is intermittant. If there has been no crash then there may be an intermittant issue with that crash sensor, or the crash sensor cicuit wiring. The fault code may be cleared to see if the issue returns. The companion code to a 54 is a code 14. When there is a short that occurs, the lamp should flash a 14 at first, then begin flashing the 54 when the short goes away.
