Bonsoir à tous,je vient d'acheter un cherokee 2.5 l ess mais sens allumage ( meme pas une etincelle grrrrrrrrr )J'ai tester la bobine;pmh et les connecteurs de raccord de fille voir si il y avais pas de ver de gris et tjr rien.Pouvez vous me donnez quelque conseil pour moi le remettre en route.Merci

quelle année le XJ ?

a tu un voyant check-engine lorsque tu met le contact?

Un problème du même genre si cela peut t'aider

Pour les tests copyright à Mr Jean Phi

bonsoir à tous,il et de 1993 et encore une journee de plus dessus bonne soiree

Et oui j ai le voyant check-engine allumer

bien!

alors tu prend un stylo et une feuille de papier.
tu te met au volant.
et tu met le contact 3x de suite (sans demarrer) la 3e fois tu laisse le contact allumé.
et puis tu commence a compter le nombre de fois que le "check-engine" clignote.

par ex CODE 17 ( 1x cligno...2 sec.Pause...7x cligno) le code suivant viens env 4-5 sec plus tard.
normalement il termine avec 55
apres tu nous dis les codes que tu a eu, et on regarde.

bonsoir,je te remercie je vais faire ça au levée du jours merci

T'as oublié un code Grim
C'est le code Fartami quand ça marche plus du tout

bonjour,je vient de regarder et il clignote 22 fois donc je vous remerie de me donner conseille pour moi avoir un vehicule roulant merci

ok je te remercie je vais voir ca demain mais c'est vraiment une prise de tete,j'ai hate que ca fonctionne pour que je puisse rouler bonne soiree

bonjour au jeepers,aprés quelque temp d'etranger me revoila pour mon sousi je vais filmer cette sequence et la mettre sur you tube et vous donnez l'adresse,et attendre que quelqu un me dit se que ca peut etre merci

voici l'adresse pour m'aider a retrouver les codes des checks merci http://www.youtube.com/watch?v=WZs4545Bras

Pour moi les codes que j'ai trouvais sont 12,33,21,22,24 et fini par 55 pour me mettre en confiance pouvez vous me dire si je me suis pas tromper merci

Code 12-Memory to controller has been cleared within 50-l00 engine starts.
=> tu a debranché la batterie,

Code 33-Air conditioner clutch relay circuit-open or short detected in
the air conditioner clutch relay circuit. If vehicle doesn't have air
conditioning ignore this code.
=> le relais de la clim... si t´as pas de clim, OK

Code 21-Oxygen sensor signal-neither rich or lean condition is detected from the oxygen sensor input.
=> sonde lambda.. indique trop riche ou trop pauvre

Code 22-Coolant voltage low-coolant temperature sensor input below the
minimum acceptable voltage/Coolant voltage high-coolant temperature
sensor input above the maximum acceptable voltage.
=> voltage de la sonde de temperature d´eau hors normes.

Code 24-Throttle Position sensor voltage high or low.
=> tps voltage trop important

Code 55-End of message.
=> fin des messages

perso je part du principe que le capteur de position du papillon deconne.
faudrai le changer pour voir ce que ca donne. (s´il deconne, la jeep ne demarre pas)

moi aussi , les autres defauts sont pas plus important que ca .
le papillon ne s'envolle pas

bonjour merci pour les reponses je vais y regarder

cela pourrais ne pas donner des etincelles au bougie

je te remercie bien

bonsoir,voila j ai verifier le capteur et il fonctionne tres bien, pouvez vous me donnez encore des renseignements pour que je puisse avoir au-moins des l'etincelles aux bougies merci

bin alors il faudrai changer le capteur point mort haut.
ou au moin verifier les connexions.

bonjour je te remercie je vais commende ça merci
