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.

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.

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.

If the fault is still present, carry out the following checks:
The inlet line must be perfectly sealed, from the throttle valve to the cylinder head.
Check:
–the condition of the air filter,
–that the air inlet circuit is not blocked,
–the sealing between the throttle valve and inlet manifold,
–the manifold pressure sensor sealing,
–the fuel vapour absorber bleed, which must not be jammed open,
–the fuel vapour absorber bleed system sealing,
–the brake servo system sealing,
–the cylinder head oil vapour recovery system sealing,
–the sealing between the inlet manifold and cylinder head,
–the exhaust pipe sealing between the cylinder head and catalytic converter.
Repair if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRFollow the instructions to confirm repair:
- If the fault is present, continue to deal with the fault.
- If the fault is stored, ignore it.
Deal with any other faults.
Clear the stored faults.
