Toyota Corolla Cross: Front Radar Sensor System

 Internal Control Module Random Access Memory (RAM) Error Data Memory Failure (P060444)

MONITOR DESCRIPTION The ECM continuously monitors its internal memory status. This self-check ensures that the ECM is functioning properly. The ECM memory status is diagnosed by internal mirroring of the main CPU and sub CPU to detect Random Access Memory (RAM) errors. If outputs from these CPUs are

 Manifold Absolute Pressure - Barometric Pressure Correlation (P006900)

DESCRIPTION The E.F.I. vacuum sensor assembly installed to the intake manifold detects the intake manifold pressure using a built-in sensor. An atmospheric pressure sensor is built into the ECM. When the engine is stopped, the value of the E.F.I. vacuum sensor assembly and atmospheric pressure sen
