Hva betyr feilkoden?
The ECM keeps watch over the idle control, meaning how steadily the engine holds its speed when the car stands still. If idle speed is lower than expected, fault code ECM-151B is set. Common causes are a blocked fuel filter or low fuel pressure, which leave the engine with too little fuel at idle.
Mulige årsaker
- Blocked fuel filter
- Low fuel pressure
Hva du kan gjøre
- 1Check that the fuses for the engine control module and the fuel pump are intact; the fuse locations are often on the inside of the fuse box cover
- 2An old or clogged fuel filter can cause low fuel pressure. Have a workshop replace it if it is old
- 3If you have a diagnostic tool: activate the fuel pump and listen for it to start
- 4Clear the fault code and check whether it comes back after the engine has idled for a while
- 5If the fault remains, have a workshop measure the fuel pressure and check the fuel system
Symptomer du kan merke2
- Low idle, the engine runs slower than usual when the car is standing still
- The fault may show all the time or only now and then
