Failure at Grand Caravan 2001

Hello, for what I see with all the reference that you have given from OBD2, I came referring to the (admission butterfly "especially with several references or codes"- cyclinder 1 and 6, for lack of pressure, admission sensor that is normally on top, you do not get the suitable 5V current of the control module, highly refrinted temperature sensor.) Most fault Admission that alomejor does not open and lacks air pressure or the EGR that has been dirty, I hope to be your help. Miguel.

Hello a pair contribution to unlock heads ..

there is no spark .. is this true?
Obviously there is spark is one of the causes for the engine not to fit. Now ask and write the following question in algun notebook or where you take away. Why is there no spark?
What is the system in charge of the delivery of spark?
From there,
as the ignition system works, if you have the wiring diagram, the task will be very fesilitated, you can know what elements intervene in the spark delivery, CKP signal, that this signal reaches the ECA, I do not know it with Seresa but I think that the ignition module is in the ECA is discarding according to the diagram the elements that could be guilty. I hope you will not stir you anymore. And something little helps.

Remember that the light or between the iron of the position sensor is very important must be about 8 mm Hojo with this, since it has happened to me that they arrive at the workshop coming from others and do not find the failure because everything is fine and this is the simple cause luck and warns how you are going.

Thank you very much, your advice has been helpful, however the patient is still in a coma, in effect there is no spark or pulsations, fortunately and thanks to this page I has the exact diagrams of the truck;
is the last thing to review ... the crankshaft sensor (CKP) has no slack to adjust as in previous models and I do not know if I had already mentioned this data: as soon as I erase the 3 fault codes that appear, before giving again, with the open switch, a second spends a second and reappear to appear
. parents, and if not a hugs to their parents

Good morning do not despair, there are failures that require time and information, if you need a specific information, write me to my email, try to add the engine data, as the fault starts, and Check Engine codes, if you have them.

Greetings.
