P0369
Camshaft Position Sensor B Circuit Intermittent Bank 1
Camshaft position
Generic OBD-II
High
What it means
P0369 means the camshaft position sensor "B" signal on bank 1 is intermittent. The ECM relies on cam position to sequence fuel and spark, so a dropping signal can cause stalling, hard starting, or an occasional no-start, along with rough running. The fault comes and goes, but it should be treated as a genuine starting and driveability risk.
