PO340 CAMSHAFT SENSOR,PO305 SPARK PLUG #5,COIL,WIRE,PO177 FUEL SENSOR,PO700 TRANSMISSION,
SOURCE: My Grand Voyager keeps getting codes P1776 P1784
Code p1776 is solenoid switch valve latched in low/reverse position. Valve is located in valve body not solenoid body. The possibilities are:
the low/reverse pressure switch itself is bad
the transmission control relay output circuit is open
the control circuit (sense) of the l/r switch is open, shorted to ground or shorted to voltage.
The control relay's output is on pin #6 of the 8-pin plug of the
transmission (red wire); you could verify that the wire has 12V on it
when you are idling (and I guess I would put it in gear with the brakes
applied). Also examine/shake the wire for intermittent connection
possibility.
The solenoid sense circuit connects pin # 8 (light blue) to pin #50 of
the transmission control module. You could check that connection and
monitor it for voltage to fluctuate between 0V and some measurable V
when the trans is shifting normally, and to loose that fluctuation when
it is not, which would verify the circuit is OK.
If that proved to be OK, then I would suspect the switch isn't responding and needs to be changed.
The solenoid box is removable after you drop the pan and remove the
valve body, and so it would not seem to be an horrendous expense
(compared to a rebuild). I haven't done this myself so I can't comment
on doing-it-yourself.
I would try to find a competent independent shop that know the Chrysler
trans and discuss it with them as to the cost of replacing the l/r
pressure switch as the alternative
The code p1784 is about the switch that monitors the hydraulic pressure for
operating the low/reverse clutch of the transmission. That clutch is
called into play for all forward gears as well as reverse, so it seems
reasonable if that clutch were not working that the car wouldn't move
in any gear. I would begin by making sure that there is sufficient
trans fluid by inspecting its dipstick. If needed only use ATF +4 but
don't overfill it. Also, just on a chance, take a look underneath to
see if you see any motion of either the left or right half axles (or
one moving, but one not) which would be another reason for no motion
due to a drive shaft disconnection or some such anomaly. Other than
that, your problem could be with the Low/Reverse solenoid switch in the
solenoid pack portion of the transmission (the box on the driver's side
of the trans) being stuck. That can be repaired without removing and
rebuilding the transmission so let us hope that may be the cause. I
would have the car towed to a good independent trans shop that has a
reputation for knowing how to service the Chrysler electronic
transmission.
DTC code p0700 is a transmission control system (mill light) which is related to the other two codes mentioned above.
Testimonial: "you was very helpful on this problem you talked in words that didn't make me fell like a dumb a// I will add this site t my fovorets for your help THA"
SOURCE: 98 Plymouth breeze trouble codes
P0700 - Transmission Control System Malfunction.
P1391 - Intermittent Loss of CMP (Camshaft) or CKP (Cranckshaft).
P0725 - Engine Speed input Circuit Malfunction.
P1595 - Speed Control Solenoid Circuit Open Or Shorted
P0320 - Ignition Engine Speed Input Circuit Malfunction
I suggtes take off each sensor and test resistance in everyone (check this measure in the Service Manual), if they are out range,m just replace it.
Keep us updated.
SOURCE: 99 Breeze is running codes I need help on what I
I would replace your cam shaft position sensor. It can cause the car to start hard and run bad if it is bad. Let me know what engine you have and I will be able to tell you where it is located.
