P0367: bank-1 exhaust camshaft signal lost at low level

P0367 identifies a missing-edge condition on the bank-1 exhaust camshaft sensor with the signal low.

Documented application

2025 GM 25OBDG07A Part2 diagnostic monitor documentation; the application-matrix filename mismatch is unresolved, so no model or engine applicability is inferred.

The code alone does not identify a failed part or establish that a vehicle is safe to drive. Confirm the vehicle, reporting module and applicable service procedure.

P0367 identifies a missing-edge condition on the bank-1 exhaust camshaft sensor with the signal low. The source calls this the outlet camshaft, providing the relevant interpretation of sensor B within this documented monitor.

A revolution-based check

At least four crankshaft revolutions must occur while no new camshaft edges are detected. The signal level at the transition to no signal is shown as zero. Ignition is on, the crankshaft reference gap is detected, and reverse rotation is excluded.

The zero is a signal-state description in this table, not a published analog-voltage tolerance for every connector. Applying it as a universal exact-zero-volt measurement would add detail the source does not supply.

Missing edges differ from bad timing patterns

The adjacent P0366 entry evaluates camshaft pattern rationality, including segment length and sequence. P0367’s evidence is more specifically a signal that has stopped at the low state. A timing-pattern diagnosis should not be assumed from the circuit-low label alone.

The table specifies one-trip reporting and common enable/inhibit requirements. Verification should confirm continuing exhaust-camshaft edges relative to a valid crankshaft reference on bank 1. The code does not select a sensor, harness, or mechanical timing repair without the corresponding vehicle-specific diagnostic procedure.

Documentation and applicability

These details describe the monitor in GM’s 2025 25OBDG07A Part2 file. Its application-matrix filename does not match the download index, so model and engine applicability remain unresolved. Use the vehicle’s correct service information before applying these calibration details.
