Code P0335 2004 Toyota Highlander Description
The P0335 diagnostic trouble code (DTC) for a 2004 Toyota Highlander refers to a malfunction in the crankshaft position sensor circuit, specifically for sensor 'A'. The crankshaft position sensor is a vital component in the engine management system, as it provides critical data to the engine control module (ECM) about the position of the crankshaft. This information is essential for determining the ignition timing, fuel injection timing, and other engine functions. When the ECM detects an issue with the crankshaft position sensor circuit, it can lead to poor engine performance, misfires, stalling, and even engine failure if left unresolved.
