Salut je vient d’acheter mon s80 2001 t6 et je l'adore. Le check engine s'est allume peut de temps après mon achat, le code est p0056, p0156. Ca provient de l'oxygene sensor? mais le quelle le scanner me dit bank 2. Ensuite le code p0014. lui provient du cam ??? pouver vous me conseiller a ce sujet. Un gros merci . Ho en passant devrai-je m’inquiéter de ces code de défaillance?

Le bank2 fait référence à la deuxième sonde (post cat) qui indique probablement que ton CAT fait une mauvaise job ce qui colle avec l'âge de la voiture si tu as encore celui d'origine (catalyseur)
Pour le cam, je laisse les pros répondre
Mais bon, les codes des autos est accessoires, rien ne vaut un scan chez les pros. Vérifie; sous tout réserve, lorsqu'il s'agit de check engine, c'est gratuit au concessionnaireDernière modification par kearmith, 25 septembre 2012, 12h29.

P0056:
ECM-2B2A Rear lambda probe pre-heating, bank 2. No signal. Intermittent fault., B6284T
Diagnostic trouble code (DTC) information
Condition
The control module controls preheating by pulsing the current to the PTC-element. Pulse lengths are dependent on heated oxygen sensor (H02S) temperature.
Diagnostic trouble code (DTC) ECM-2B2A is stored if the control module registers that the signal is constantly 2.5 V, higher than 3.5 V at current pulse or lower than 2.3 V at no pulse.
The control module also registers the heated oxygen sensor (H02S) temperature by measuring resistance in the PTC-element. The probe temperature is then compared with a calculated temperature.
Diagnostic trouble code (DTC) ECM-2B2A is stored for a faulty signal if the control module registers that the actual probe temperature is lower than the calculated temperature.
Substitute value
fuel trim shut off.
Possible source
Signal missing:
contact resistance and oxidation
open-circuit in power supply from system relay.
Faulty signal:
defective heated oxygen sensor (HO2S).

P0156:
ECM-2B0A Rear lambda probe, bank 2. No signal. Intermittent fault, B6284T
Diagnostic trouble code (DTC) information
Condition
The control module checks that no faults remain in the probe or the wiring. Diagnostic trouble code (DTC) ECM-2B0A is stored if the control module registers that the signal deviates from its permitted operational range.
Substitute value
twin heated oxygen sensor (HO2S) control disabled
Three-way catalytic converter (TWC) diagnostic disabled.
Possible source
Signal missing:
open-circuit in signal cable
open-circuit in ground lead
defective heated oxygen sensor (HO2S).
contact resistance or oxidation in the connectors

P0014:
ECM-644A Camshaft reset valve. Slow control. Intermittent fault, B6284T
Diagnostic trouble code (DTC) information
Condition
Diagnostic trouble code (DTC) ECM-644A is stored in the engine control module (ECM) if the camshaft is not in the correct position. The engine control module (ECM) registers this as a fault as soon as the engine is started.
The engine control module (ECM) registers a fault and diagnostic trouble code (DTC) ECM-644A is stored in the engine control module (ECM) if the camshaft position (CMP) sensor flanker is not correct in relation to the engine speed (RPM) sensor.
The engine control module (ECM) registers a fault and diagnostic trouble code (DTC) ECM-644A is stored in the engine control module (ECM) if the camshaft does not rotate quickly enough in response to the control signal.
Substitute value
the variable camshaft is disabled
Possible source
Control too slow
open-circuit in signal cable
open-circuit in power cable
contact resistance
short-circuit to ground in signal cable
short-circuit to supply voltage in the signal cable
low oil pressure
poor oil quality
defective reset valve
mechanical fault in the Variable valve timing (VVT) unit
Fault symptom[s]
poor performance15% de rabais sur les pièces d'origine chez Volvo Pointe-Claire pour les membres CVQ VIP.
