2012 Honda Insight – No Spark After Engine Replacement
- Aug 15
- 1 min read
CUSTOMER CONCERN
The engine cranks but has no spark after a used-engine installation, and the scan tool shows no cranking RPM.
CAUSE
Inspection confirmed the camshaft-position sensor connector had been swapped with a nearby component using the same connector shape. The incorrect wire colors exposed the mix-up; the correct circuits are Yellow/Black 12-volt supply, Brown/Yellow ground, Blue crankshaft signal, and Green camshaft signal.
CORRECTION
Reconnect the correct harness connector to the camshaft-position sensor, then verify cranking RPM, ignition spark, and engine starting.
