When this code appears, it is often accompanied by "Check Anti-Pollution System" or "Check Injection" messages on the dashboard. It essentially signals that the has detected an incorrect signal or flux in the gas flow, typically linked to a pressure sensor.

Exhaust Gas Recirculation (EGR) / Turbocharger Boost. Common Symptoms: Loss of engine power or "limp mode".

A jammed or fouled EGR valve can disrupt the expected gas flow, leading to this specific "flux" error. How to Fix Code 148E22 renault 148e22

Corroded connectors or damaged wiring looms can lead to high voltage readings or signal loss, which the ECU interprets as a system fault.

Use a diagnostic tool (like Launch or CLIP) to graph the Upstream Turbine Pressure against Engine RPM . If the pressure doesn't rise and fall in sync with the RPM, there is a confirmed blockage or sensor failure. When this code appears, it is often accompanied

Intermittent sluggishness, especially when the engine is cold. "Check Anti-Pollution" or "Check Injection" warnings. Common Causes of Renault 148E22

The small tubes connecting the engine to the pressure sensor often become blocked with carbon soot . A leak in the rubber portion of these tubes is also a frequent point of failure. Common Symptoms: Loss of engine power or "limp mode"

A common culprit is the sensor that measures gas pressure before it reaches the turbine. If this sensor reports static or incorrect values, the ECU triggers 148E22.
