What does this fault code mean?

Although the code is named signal too high, it applies when the signal from the particle filter pressure sensor is incorrect. The engine control module (ECM) measures the pressure upstream and downstream of the filter and checks the signal against a calculated value. The fault gives no noticeable symptoms for the driver.

Possible causes

Loose hoses between the pressure sensor and the particle filter
Pinched or folded hoses between the pressure sensor and the particle filter
Hoses or pipes to the pressure sensor have been swapped
Damaged particle filter pressure sensor

What you can do

1Check that the hoses between the pressure sensor and the particle filter have not come loose
2Look for pinched or folded hoses between the pressure sensor and the particle filter
3Check that the connectors at the pressure sensor are firmly seated and not oxidised
4If you have a diagnostic tool, read the adapted pressure difference in live data
5Have a workshop disconnect the control module connector, measure the signal wire with diagnostic equipment and reset the adaptation

Symptoms you may notice1

No noticeable symptoms for the driver
