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

If cleaning the tubes doesn't work, the pressure sensor itself may be faulty. Automotive experts on YouTube recommend using genuine Renault sensors rather than aftermarket alternatives to ensure the ECU accepts the signal.

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

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.

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. If this sensor reports static or incorrect values,

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. typically linked to a pressure sensor.

Repairing this fault often involves cleaning rather than expensive parts replacement.

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.

Inspect the rubber hoses for cracks or leaks. For metal tubes, carbon buildup can be removed using DPF cleaning fluid and a mechanical wire to break up the soot.
