Code P1537 Mazda Description
The P1537 Mazda code indicates that there is an issue with the Intake Manifold Runner Control (IMRC) system, specifically that it is stuck open.

When the intake manifold runner control is stuck open, it means that the runner is not able to adjust properly, leading to an incorrect air-fuel mixture entering the engine. This can result in poor engine performance, reduced fuel efficiency, and potentially even engine misfires.
