Important safety note
Technical information and practical tips have been compiled by HELLA in order to provide professional support to vehicle workshops in their work. The information provided on this website is intended for use by suitably qualified personnel only.
If there are complaints regarding the engine performance or if the engine bucks, a faulty fuel temperature sensor may be the cause (Fig. 1). Often the error code 27277 and/or 27064 (signal implausible) is also stored in the engine control unit.
The measured values of the fuel temperature sensor are included as a correction variable in the calculation of the injection duration and the injection timing. If an error occurs here, this may have an effect on the engine performance. Sometimes the engine jerks and the engine control lamp comes on.
In some cases, fuel enters the temperature sensor as a result of an internal leak (Fig. 2). Corrosion of the plug contacts also occurs in some cases. In order to remedy the problem, the temperature sensor should be replaced. Corroded contacts should also be cleaned or replaced.
After replacing the sensor, the error memory should be cleared using a diagnostic device, e.g. the Hella-Gutmann Mega-Macs series, and a test drive carried out.
