Circuit Description
This test checks for 24X signal at a logic high condition. The fault could be induced by the failure of either crankshaft position "A" or "B" sensor input signal to the IC module. Under such a condition, the IC module would force the 24X signal high. This DTC will also set if the 24X signal is shorted to voltage externally. If either condition is met DTC will set.
