With the ignition on, and engine switched off for over 1 minute:
Display the parameter PR038 Rail pressure in the Fuel circuit, Engine control function tab,
–If the value is below 50 bar, the sensor is in order.
In this case, contact the Techline.
–If the pressure is above 50 bar, replace the rail pressure sensor and tighten to 35 ± 5 Nm.
Follow the recommended safety advice (see cleanliness advice).

Check the mechanical condition of the accelerator pedal:
–locked in full load position,
–with the pedal blocked by an external component.
Repair if necessary.
Vary the position of the pedal and refer to the conformity check in order to check the operating values of the
accelerator pedal potentiometer.
If the values displayed are inconsistent, replace the accelerator pedal potentiometer.

NOTESThe brake pedal has been depressed while the accelerator
is depressed and jammed.
Check the brake light switch.
This is a test procedure designed to detect an accelerator pedal that is jammed in the depressed position. It
monitors the accelerator pedal in relation to the brake pedal.
If the test procedure detects depression of the brake pedal over 600 ms, it registers a fault which is stored in the
computer. While this fault is present (both pedals depressed simultaneously) the engine switches to limp home
mode and the engine speed is set at 1,400 rpm.
Once the fault is no longer present (e.g. brake and accelerator pedals released) safe mode is deactivated and the
engine immediately regains its ability to respond to speed/torque requests.
This fault may occur even if the accelerator pedal is not jammed, if there is driver error during use:
- "Heel-and-toe" type driving,
- Vehicle with driving school option,
The procedure in this case should be to clear the fault and take another reading.
If the fault is still present, check the mechanical condition of the accelerator pedal:
–locked in full load position,
–with the pedal blocked by an external component.
Repair if necessary.
Vary the position of the pedal and refer to the conformity check in order to check the operating values of the
accelerator pedal potentiometer.
If the values displayed are inconsistent, replace the accelerator pedal potentiometer.
AFTER REPAIRDeal with any faults.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after an attempt to start engine.
Special notes:
It is impossible to start the vehicle.
If the fault is present, the level 2 warning light will light up.
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
Check the UCH connections.
Check the injection computer connections.
Repair if necessary.
Test the multiplex network (see 38B, Multiplexing) and carry out a complete fault finding on the UCH.
Refer to the UCH Technical Note (see 87B, Passenger compartment connection unit) if the fault is displayed
as present.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
