Power Steering Pressure Sensor Circuit Intermittent

What This Actually Means
In plain language — no jargon

Your power steering pressure sensor is sending inconsistent signals to the engine computer, like a radio that keeps cutting in and out. The ECU can't reliably read how much pressure is in the steering system, so it triggers this fault code.

Embedded Systems Insight
What the ECU/ECM is actually computing

The ECU monitors the power steering pressure sensor's voltage signal, which should vary smoothly between 0.5V and 4.5V depending on steering demand. The computer flags P0560 when it detects dropout, noise, or erratic fluctuations in this signal that don't match expected pressure dynamics.

Voltage & Parameter Thresholds

Parameter Normal Range Fault Condition
Sensor Voltage 0.5V to 4.5V (steady) Intermittent drops, spikes, or noise
Signal Continuity Continuous smooth transitions Dropouts or signal loss lasting >100ms

Diagnostic & DIY Fix Guide
Check these in order — from cheapest to most complex
1
Power steering pressure sensor connector
Inspect and reseat the connector at the sensor; corrosion or loose pins are the most common culprits.
2
Power steering pressure sensor wiring harness
Check the wiring for cracks, pinches, or chafing along the entire run from sensor to ECU.
3
Power steering pressure sensor
Replace the sensor if voltage signal remains intermittent after cleaning connectors and inspecting wiring.
