Infiniti EX35, EX37 (J50) typical problems with electrical, wiring, sensors
-
Faulty Sensors: Malfunctions in sensors, particularly the camshaft and crankshaft position sensors, can lead to poor engine performance and unexpected shutdowns. Keeping sensors clean and performing regular diagnostics can help detect early issues.
-
Battery and Charging System: Weak batteries and alternator issues may cause frequent starting problems. Regular checks and maintenance of battery health and alternator output are recommended.
-
Wiring Harness Wear: Due to the engine bay's high temperatures, wiring harnesses may degrade or loosen, leading to connectivity problems. Inspecting and securing connectors and wiring regularly can prevent intermittent electrical failures.
-
Malfunctioning Fuses and Relays: Fuse and relay issues, especially in the fuse box under the hood, can lead to specific system failures (e.g., headlights, AC, or fuel pump). Regular inspection of fuses and replacement as needed can reduce these occurrences.
-
Corroded Grounding Points: Poor grounding connections often lead to flickering lights, sensor misreads, and electronic instability. Cleaning and securing ground points can prevent many electrical issues.
