2000 Ford Taurus 3.0 Engine Codes

Question

what do the codes p0720 p0722 p0460 p1413 p0301 p0302 mean that my 2000 Ford Taurus 3.0 needs?

Answer 1

P0720 Output speed sensor circuit malfunction

P0722 Output speed sensor no signal

P0460 Fuel level sensor circuit malfunction

P0413 Secondary air injection system switching valve A circuit open

P0301 Misfire number 1 cylinder

P0302 Misfire number 2 cylinder

The code P0722 and P0720 is for the transmission with out the output speed sensor signal the transmission will not shift properly, having no signal inspecting for proper connection of the speed is needed, P0460 is part of the fuel pump having a fuel level sensor malfunction result with a incorrect reading of the fuel level, The ECM uses the fuel level to determine when it will test for a evap leak, the fix for this is usually with the fuel pump assembly, As for the misfire condition , misfire can be caused by mechanical condition , ignition coil malfunction to sparkplugs to fuel injector, because cylinder 1 and 2 are right near each other you need to rule out a mechanical condition before repairing the misfire of cylinder 1 and 2

Comments

The coil and all  spark  plugs  and  wires  were changed  and cylinder  1 and 2 still misfiring .

Rule out a mechanical condition by perfroming a compression test or better a leak down test of cylinders 1 and 2.
