I have a 2004 Chrysler Concorde LXI 2.7 Eng. Got Check Engine light twice with PO344 code (Cam Shaft). Dealer could not find problem and reset computer twice. Now I am getting error codes PO700and P1776 (Transmission). Dealer still can't find problems and has reset computer. Any advice?
Model: Concorde LXI
Hello and welcome to JustAnswer!
Have any actual attempts to repair either problem been made?
no they are confused because first the error codes were cam shaft related and now are transmission. Thet only checked wiring
The two problems are not related.
P0344 sets when the powertrain control module is seeing an intermittent signal from the camshaft position sensor. This can be the cam sensor, wiring, connections, powertrain control module, a cam timing issue, etc. By far the most common cause of this code is the cam sensor itself, and if the wiring and connection are visibly ok then the sensor will need to be replaced.
P0700 sets in the engine controller when there is a code stored in the transmission controller (TCM). The code stored in the TCM is the P1776.
P1776 sets when the solenoid switch valve in the valve body gets stuck in the low/reverse position or the TCM thinks that it does. This can be caused by the valve actually sticking, a failed low/reverse pressure switch, wiring between the trans and TCM, or the TCM. While it's not uncommon for the valve to actually stick, the most common cause of this code on these vehicles is a failed pressure switch. The pressure switches are contained in the solenoid pack mounted on top the valve body in the trans. There were a number of solenoid packs that had suspect pressure switches and were identified in a service bulletin regarding this code. If I was repairing this in person I would disassemble the valve body to inspect the solenoid switch valve and it's bore, and then replace the solenoid pack while it's apart.
For the transmission reply do you mean low in the forward drive position. Reason I ask is the cars motion was forward and not in reverse. In fact when the light came on the car was running great. Only when I slowed down to about 15 - 10 mph did the car skip. Than ran OK, then skip once the next day when slowing down to 15-10 mph.
Low/reverse is the name of a clutch inside the transmission. The low/reverse solenoid controls it, and the low/reverse solenoid controls the torque converter clutch using the solenoid switch valve in the valve body. The P1776 sets when the solenoid switch valve sticks in the low/reverse position or the TCM thinks that it doesn't when it's not.
Do you recall what the SB number was for the stuck valve
The TSB was for suspect pressure switches. The number is XXXXX
