Code P1512 Mazda Description
The P1512 code for Mazda vehicles indicates a problem with the Intake Manifold Runner Control (IMRC) system being stuck closed on Bank 1. The IMRC system is responsible for adjusting the length of the intake manifold runners to optimize airflow into the engine based on driving conditions. When the intake manifold runner is stuck closed, it can lead to a disruption in the air-fuel mixture entering the engine, resulting in poor engine performance.
Common Causes of P1512 Mazda
- Faulty IMRC actuator or solenoid
- Carbon buildup in the intake manifold
- Damaged wiring or connectors
- Malfunctioning intake manifold runner control valve
- Electronic control module (ECM) issues
Symptoms of P1512 Mazda
- Reduced power and acceleration
- Rough idling or engine misfires
- Decreased fuel efficiency
