• Faulty metering oil pump stepping motor
• Wiring issues such as shorts, opens, or corrosion in the circuit
• Defective Engine Control Module (ECM)
• Faulty connectors or terminals related to the oil pump circuit
• Oil pump mechanical failure

DTC P1692 seriousness

DTC P1692 can be serious as it may lead to inadequate oil pressure and flow, which can cause significant engine damage over time. If left unaddressed, the symptoms may worsen, potentially resulting in engine failure. It is advisable to diagnose and repair this issue promptly to avoid costly repairs and ensure the longevity of the engine.
