What sensors influence ignition timing?
What sensors influence ignition timing?
The manifold absolute pressure (MAP) sensor measures intake vacuum, which the PCM also uses to determine engine load. The MAP sensor’s input affects ignition timing primarily, but also fuel delivery. Knock sensors are used to detect vibrations produced by detonation.
What should the ignition timing be on a Ford 351?
Igniton timing should be checked two ways at 2,500 to 3,500 rpm: vacuum advance connected and disconnected. Total ignition timing with vacuum advance connected should be no more than 36 degrees BTDC. At idle, it should be 6 to 12 degrees BTDC.
Where is the timing marker on a Ford 6 cylinder engine?
Move to the engine compartment and find your timing marker located on the driver’s side of the engine. It is attached to the timing cover, just above the crankshaft pulley. A typical marker shows “12-8-4-0.”
Where is the timing number on a Ford F150?
Adjust the distributor until the proper reference number is obtained. These numbers vary from engine to engine. The timing setting should be printed on the emissions sticker near the radiator. Set the timing, turn off the engine, remove the timing light, tighten the distributor bolt and hook up the vacuum advance hose.
What happens if your ignition timing is wrong?
Proper ignition timing will, of course, give optimum performance. Improper timing can result in poor power and fuel economy, or a noisy engine when accelerating. Checking your timing is a pretty straightforward process, but you will have to invest in an inductive timing light.

What should the ignition timing be on a Ford 360?
The ignition timing for a manual transmission required a setting with the warm idle speed of 850 revolutions per minute (rpm), all accessories off, transmission in neutral, emergency brake engaged and the distributor vacuum hose disconnected and plugged.
Where are the timing marks on a Ford 351?
Find the timing marks on the harmonic balancer. If you can’t see them, bump the engine over with the starter until you can see them. The marks will read “BEFORE-30-20-10-0-10-AFTER,” with small lines between the numbers. The lines represent an increment of 2 degrees.
