Hi,
Check power and signal on the pressure sensor, you should find with sensor disconnected: pin 1 ground / pin 2 Signal 5V / pin 3 Power 5V

Sensor is 1032 and goes to big black connector of the ECU.

With your Clip, to see what means the DTC definition check the white square box on the left of the DTC line!

hello Louislesinge,
thank you for your interest, this is what I do not do I will try with that But I changed the high pressure kit (rail, pump, injector with its sensor) all the sensor when I disconnect the sensors i find another error code has appeared , I don't know which sensor gives this error I checked all the connector sensors up to ecu

It's an unreasonable problem

Re,
Sorry, did not read very well your post, problem is on the regulator on the pump, not on the sensor!
So, on the pump there is only one regulator, this is number 1105. It's feeded under 12V from fuse F08 and negative command is on PIN2 from the ECU, big black connector PIN D4
First, with ignition ON connect 10W bulb between PIN 1 and ground, light should be full ON, if ok connect bulb between + batt and pin 2 (or between PIN 1 and 2 if 12V on PIN 1 ok): bulb should light ON lower than normally feeded.
Of course if command or +12V misses check continuity of the wires.
If all ok and DTC is permanent and can't be deleted or goes on every time you turn ignition ON, ECU should be out of order.
You can have a look at - Bosch repair service - (do Google search), there you can type your 0281XXXXXX number and watch what are the common failures...

Hi,
if the whole mechanical part is good
I already had this problem after reading via OBD with original kess,
error is in eprom
I solved the problem with a dump of another calculator of same reference virginized and recoded immo etc
or go to dealer for update
in my case already last update in ecu

Hi Louislesinge
Thank you for helping me with my problem, I check everything visible and check the continuity of the wires from the sensors to the unit everything is fine, I still have to test the frequency with oscilloscop but I have not given them,
thank you very much

Hi esseThank you very much for participating on solution of my problem, I control all the mechanical part, is good, Your words are true and close to my problem I will follow in this direction
if you can help me, how i can do a update? if with CAN CLIP or other tools, and if you have a blank eprome

Thank you

Hi,
post eprom file from ecu and i ll help you

**esse** · 22nd March, 2021, 11:25 PM

Yes you can with clip online or with the right update file from CD reprog

**redonerj** · 22nd March, 2021, 11:37 PM

Hello Esse Thank You
I have new news, when I wrote another EEPROM from another Renault, the error disappeared but without beginning because it is not eeprom own

Yes you can, connect charger to car, disconnect CLIP from WIFI and try. But first ECU must be unlocked so you need to write original Eeprom.

Greetings,

Hi Louislesinge
thank you
I will try this way, thanks for the help

**redonerj** · 25th March, 2021, 07:43 PM

I have bad news i do reprog to the ECU But it stops at 11% and she didn't want to read after that read it just with boot mode any other solution, please

**Louislesinge** · 26th March, 2021, 10:15 AM

Hi,
Try this:
Do you mean you lost communication with ECU?
If yes, is it reconized under reprogramming mode?
Go until Clip asks you to select ECU update, don't select it yet, turn ignition off, wait a few seconds, turn ignition ON and send update.

Battery must be over 12,70 (big charger or another car with engine running and jumped is required) , engine temperature must be under 60°.
Is your Trafic manual or automatic gearbox?
Greetings,
