← TechnologyWhich risk increases when intake manifold pressure sensors malfunction during fuel injection?
A)Catalytic converter thermal overload✓
B)Reduced cylinder valve float
C)Crankshaft torsional vibrations dampen
D)Increased connecting rod buckling
💡 Explanation
Overly rich fuel mixtures stress the catalytic converter because incomplete combustion causes excess hydrocarbons. The rich mixture results from faulty sensor data causing continuous fuel enrichment, therefore the converter overheats rather than proper combustion, and the core melts.
