The fault codes help to identify the fault in the vehicle. But sometimes short descriptions of fault codes can confuse a little more than telling what the problem is.
The DF005 fault code received on Renault vehicles is one of them. In order to be able to determine what this fault code means, the mechanic must be experienced and knowledgeable and be familiar with the complaints experienced in the vehicle.
The DF005 fault code synchronizes with the P0335 fault code and tells us that there may be a fault with the crankshaft position sensor. However, different Renault models and different scanning devices give different explanations for the DF005 fault code.
Possible problems with the vehicle with the Renault fault code DF005:
- There are drownings in the vehicle
- Failure to reach high revs
- Engine failure when the starter is pressed
- The vehicle stops, the engine does not start until it cools down
- Noisy operation of the engine
What is the DF005 Renault fault code?
Brief description of the DF005 fault code:
Although the short description of this code is in the form of “Crankshaft position sensor circuit”, there may also be the following explanations regarding the DF005 fault code in fault scanning devices:
Transmission related: Oil pressure sensor circuit
Headlights: Computer startup error
UCH mastermind: Card error
Related to the parking system: Right internal sensor failure
ECU: Internal electronic fault
A malfunction related to the crankshaft position sensor circuit may cause the above problems, or one of the above problems may cause the crankshaft position sensor to produce abnormal data.
In order to interpret the DF005 fault code well, it is necessary to know the complaints experienced in the vehicle and which warning / fault lights are lit on the instrument panel.
Reasons for the DF005 fault code:
The task of the crankshaft position sensor is to send information such as crankshaft speed information, position angle information to the ECU.
The crankshaft position sensor mounted inside the crankshaft or engine block creates an electrical wavelength pattern that changes with engine speed as the crankshaft rotates.
The reasons for generating the DF005 fault code;
- The signal plate is damaged,
- Timing belt/chain failure,
- A short circuit in the sensor cables or looseness in the connection,
- There is a weakness or interruption in the electricity coming to the sensor,
- An ECU-induced problem,
- Crankshaft position sensor malfunction,
DF005 Renault fault code solution
- The crankshaft position sensor and wiring are checked. There may be wear and tear on the signal plate or cables over time, they are checked.
- If all of these are intact, it must be confirmed that electricity is coming to the crankshaft position sensor in a healthy way. For this, the power of the battery is measured, it is checked whether the polar heads are rusty or loose, the battery charging system is checked.
- The timing belt needs to be changed at December intervals and neglecting this may cause the crankshaft position sensor to detect abnormal data and cause the DF005 fault code.
- If the timing belt/chain needs to be changed, it is replaced.
- If no tangible problems were encountered when the vehicle was examined, the possibility of brain failure is emphasized.
- If the headlights are not working in the vehicle or some electronic components are not working, there may be an UCH brain card malfunction or there may be a software error caused by the ECU.
- Such problems can be corrected by software update and card replacement if the card is defective.
