Power steering assistance has reduced or failed completely, making the steering wheel very heavy and difficult to turn. Can appear gradually or suddenly. This fault code is stored when the engine control unit detects a specific fault condition. Common causes include sensor failures, wiring faults, and component wear. Always read additional fault codes before replacing parts — multiple codes together provide a clearer diagnosis. Clear the code after repair and test drive to confirm the fault does not return.

Newer car with electric power steering. Steering went heavy suddenly with EPS warning light. No fluid to check on these. Module had failed — replacement module from dealer and programming. £380. Electric PAS is reliable but when it fails there's no cheap fix.
Parts replaced: EPS control module
Started as a whining noise then the steering got suddenly very heavy. PAS pump had failed. Recon unit was £95, labour about £80. Flushed the system at the same time. Steering back to normal.
Parts replaced: Power steering pump (remanufactured), PAS fluid
Steering got progressively heavier over a few weeks. Checked PAS fluid reservoir — almost empty. Topped up with the correct fluid. Steering normal immediately. Found the leak was from a loose hose clip at the reservoir. Tightened it and no more loss.
Parts replaced: Power steering fluid, hose clip
