# Service bulletin 01146120352352

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10228391
- Published by NHTSA: 2023\-01\-03
- Manufacturer's number: 01146120352352
- Manufacturer's date: 2014\-01\-23
- NHTSA component: FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING

## NHTSA's summary

The fuel metering valve of the high\-pressure fuel pump is controlled by a specific on/off ratio. If there is a low system voltage, the on/off ratio may not be enough to keep the fuel metering valve constant in all areas. In such a situation, the fuel metering valve is deactivated and the high\-pressure fuel pump switches to full supply mode. Because the increased rail pressure does not match the respective driving situation, the DTC appears.
