Exhaust Gas Recirculation Sensor A Circuit Intermittent

Yes, you can generally drive normally. The intermittent nature means the fault comes and goes, and the engine usually runs fine between episodes. However, repair is recommended to prevent worsening.

The intermittent fault is typically caused by a loose connection or partially broken wire. Temperature changes, engine vibration, and road conditions can cause the connection to fail temporarily.

Start with inspecting and cleaning connectors. Many intermittent faults are resolved by reseating the connector and applying dielectric grease. Replace the sensor only if connector and wiring repairs do not fix the issue.

The OBD II regulation requires the system to flag EGR when flow deviates from the manufacturer's specified rate — in either direction, too much or too little — by enough to push emissions past 1.5 times the FTP standards; and, where no EGR fault could do that, when there is no detectable EGR flow at all (Title 13 CCR 1968.2, section (e)(8.2)). Note that excess flow is a malfunction too, which is why an EGR code does not automatically mean a blocked passage. This is the threshold the monitor is designed around, not a description of your specific fault — the regulation says what the system must detect, not how to find it on your vehicle.
