TDC sensor:
The angular position is measured using a magneto-inductive sensor triggered by the machined teeth on the engine
flywheel. This sensor gives the engine speed as well as the position of the crankshaft for injection.
Refrigerant pressure sensor:
Its role is to measure the refrigerant pressure in the air conditioning circuit.
Engine coolant temperature sensor:
The engine coolant temperature sensor informs the computer of the engine coolant temperature.
Air temperature sensor:
The air temperature sensor is fitted inside the inlet manifold and informs the computer of the temperature of the air
taken in by the engine.
Catalytic converter:
The role of the catalytic converter is to convert pollutant gases into harmless gases.
Cruise control/speed limiter on/off switch:
This switch is used to turn the cruise control/speed limiter on or off.
Fan unit relay:
This relay actuates the motor-driven fan assemblies when a temperature threshold has been exceeded.
Accelerator potentiometer:
The accelerator potentiometer informs the computer of the position of the accelerator pedal (engine load).
Clutch pedal switch:
The clutch pedal switch informs the computer of the clutch pedal status.
Inlet air temperature sensor:
Its role is to measure the air temperature in the inlet circuit.
Pinking sensor:
Its role is to check for pinking in the combustion chamber.
Oil level sensor:
This sensor measures the level of oil in the engine and sends this information to the computer.

Fault finding – Replacement of components17B
SIM 32 Injection
Program no.: D3
Vdiag No.: 44, 4C, 50
and 54
PROCEDURE:
Before any computer programming, only Vdiag 54 and 50 (see previous page):
–Run the command SC003 'Save computer data.
Any time the computer has been programmed
–Switch the ignition off and then on again.
–Select the UCH domain using the diagnostic tool.
–In repair mode, run the command SC017 "Programming the injection immobiliser code" and follow the
instructions given by the diagnostic tool.
–Switch the ignition off and then on again.
–Select the INJECTION subgroup and check status ET341 Immobiliser code programmed.
–Run the command SC001 ''Write saved data" Vdiag 54 only.
IF ET341 = YES
–Start and then stop the engine (to initialise the computer) and wait 30 seconds.
–Switch the ignition back on and use the diagnostic tool to carry out the following steps:
–Run the command VP010 Write VIN.
–After injection system programming, stored faults may appear on other computers. Clear the memory of
these computers.
IF ET341: NO
–Re-run command SC017 and follow the instructions given by the diagnostic tool.
2. COMPUTER REPROGRAMMING OPERATIONS
When replacing or removing the TDC sensor, program the engine flywheel ring (see Configurations and
programming).
3. REPLACING THE MOTORISED THROTTLE VALVE
When replacing the throttle valve, program the throttle stops (see Configurations and programming).
4. REPLACING THE MOTORISED THROTTLE VALVE
When replacing the throttle valve, program the throttle stops (see Configurations and programming). IMPORTANT:
AFTER A PROGRAMMING OPERATION, DO NOT DISCONNECT THE BATTERY FOR AT LEAST
30 MINUTES (to carry out other work on the vehicle).
IMPORTANT:
Never drive the vehicle without having programmed the throttle stops.

2. PROGRAMMING
Flywheel target programming
(To be carried out when replacing or removing the TDC sensor).
The coolant temperature must be over 35˚C.
–Carry out an initial deceleration with injection cut-off (feet off the brake, accelerator and clutch pedals) between
3500 and 3000 rpm, in 3rd gear for at least 5 seconds for manual gearboxes.
–Decelerate a second time with injection cut-off (feet off the brake, accelerator and clutch pedals) between 2400 and
2000 rpm, in 3rd gear for at least 5 seconds for manual gearboxes.
Check the programming with ET089 Programming flywheel target: Performed.
Programming the throttle end stops
After replacement of the computer or the motorised throttle valve, with the ignition on, wait 30 seconds so that the
computer can program the Upper and Lower limits and then switch off the ignition and wait 30 seconds for the end of
the "Power Latch", so that the computer can store the programmed limits. Check the programming with ET051
Programming throttle stops: Performed.
Programming the alcohol level (only for vehicles running on Ethanol or E85 fuel)
Fuel recognition is carried out by observing the drift of the richness controller.
This can only be performed if the mixture regulation is looped (ET300 Mixture regulation).
Programming procedure:
–start the engine,
–wait for the engine coolant temperature to reach 75˚C and then check using the parameter PR064 "Coolant
temperature",
–run the engine at 1500 rpm for a period of at least 5 minutes,
–check that the programming has been carried out using status ET671 Alcohol level programming and
parameter PR743 Estimated alcohol level in tank,
–the programming is saved when the ignition is switched off. Note:
After replacement of the throttle valve run the command RZ005 Programming to erase any recorded
programming.
Note:
When the injection computer has not recognised the fuel composition, operation is faulty.

OR
STOREDCOMBUSTION MISFIRES ON CYLINDER 1
1.DEF: Destructive misfiring
2.DEF: Polluting misfiring
3.DEF: EOBD
NOTESPriorities when dealing with a number of faults:
Firstly, deal with the following faults:
–ignition:
–DF361 Ignition coil circuit 1-4,
–DF362 Ignition coil circuit 2-3
–fuel supply circuit:
–DF026 Cylinder 1 injector circuit
–DF027 Cylinder 2 injector circuit,
–DF028 Cylinder 3 injector circuit
–DF029 Cylinder 4 injector circuit,
–DF085 Fuel pump relay control circuit,
–engine flywheel signal faults:
–DF154 Flywheel signal sensor circuit,
–DF457 Engine flywheel target.
Conditions for applying the fault finding procedure to stored faults:
The fault is considered present when the engine is running.
Special notes:
1.DEF: As soon as the fault is detected, the injection is cut for the faulty cylinder(s) to
limit the rise in temperature inside the catalytic converter. The OBD warning light
flashes for as long as the fault is present.
2.DEF and 3.DEF: The OBD warning light is permanently illuminated.
Misfiring on
cylinder 1 only
The fault is probably due to a component that can only affect this cylinder:
–check the valve clearance,
–check the cylinder 1 injector,
–check the condition and the conformity of the spark plug for cylinder 1,
–measure the compression of cylinder 1.
SIM32_V44_DF059/SIM32_V4C_DF059/SIM32_V50_DF059/SIM32_V54_DF059
AFTER REPAIREnsure that all the faults have been dealt with.
Clear the stored faults. Do not clear the programming.
To check that the system has been properly repaired:
- there must be no further electrical faults,
- programming has been carried out,
- the engine should be warm (minimum temperature 75˚C)
Run the engine at idle speed with all electrical consumers drawing power for 15 minutes.
