P0183 Fuel Temperature Sensor A Circuit High

NOTE:

Only if engine does not start: 

z

Operate starter for approx. 6 seconds. Do not switch ignition off afterward. 

NOTE:

z

The DTC table is sorted by SAE codes.  

z

"Emission"-relevant malfunctions are additionally indicated in the 
instrument cluster via the Malfunction Indicator Lamp (MIL). See 
MALFUNCTION INDICATOR LAMP (MIL) IN INSTRUMENT CLUSTER .  

z

In Diagnostic mode 2, it can be determined at which operating condition a 
malfunction was detected and stored by the control module for Diesel-
Direct fuel injection system. See DIAGNOSTIC MODE 2: CHECK 
OPERATING CONDITIONS .

Explanation: 

z

P0183 = SAE diagnostic trouble code (malfunction identification number).  

z

Fuel Temperature Sensor A = faulty circuit or malfunctioning component.  

z

Circuit High = malfunction type as text  

Diagnostic mode 4: Reset/erase diagnostic data 

Function 

This diagnostic mode performs the following functions: 

z

all emission relevant malfunctions in DTC memory will be erased,  

z

the operating conditions at which a malfunction was stored will be reset. See DIAGNOSTIC MODE 2: 
CHECK OPERATING CONDITIONS
 .  

z

all adaptation values are being reset,  

z

all test results of the diagnostic functions are being reset.  

Requirement 

z

DTC memory was checked. See DIAGNOSTIC MODE 3: CHECK DTC MEMORY .  

Work procedure 

z

Connect diagnostic tester. See DIAGNOSTIC TESTER, CONNECTING .  

z

Start engine and let run at idle.  

z

Under address word 33, select "Diagnostic mode 4: Reset/erase diagnostic data."  

Erased or reset: 

z

Number and content of the DTC memories,  

z

Operating conditions,  

z

Adaptation values,  

z

Test results.  

z

End diagnosis and switch ignition off.  

z

Generate readiness code. See READINESS CODE, GENERATING .  

Diagnostic mode 6: Check test results of components that are not continuously monitored 

Function 

This diagnostic mode displays the test results of emission relevant components and systems which are not 
continuously monitored.
