Dodge Grand Caravan P0304 Causes

Cylinder 4 misfires can be caused by many reasons from a faulty ignition system, fuel system, or internal engine failure. The most common reason for this to happen is faulty or worn-out spark plug coil packs, especially if it`s been a while since you had a tune-up.

Common signs include lacking power when accelerating, rough or slow idle, stalling, inability to shift up, and the Check Engine Light coming on.
What the P0600 code means. P0600 means that the ECU has lost the connection with one of its many controllers more than once. When this code is set the ECU triggers the Check Engine Light to be displayed on the dashboard and a failsafe mode enacted. The failsafe mode is to prevent further damage and protect the vehicle.
P1745 Transmission Line Pressure Too High

The transmission is not designed to operate in open-loop line pressure control for an extended period time. This DTC is intended to protect the transmission.

There are two main types of throttle position sensors: potentiometer-based and Hall effect-based.
The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.
The Throttle Position Sensor is usually located on the butterfly spindle/shaft so that it can directly monitor the throttle position. Will a malfunctioning Throttle Position Sensor cause a check engine light? In most cases, the Check Engine Light is illuminated if a Throttle Position Sensor failure is detected.
The TPS is usually mounted on the throttle body (the housing that contains the throttle valve).

Difference between a 2011 Dodge Grand Caravan SE and 2011 Dodge Grand Caravan C/V besides the seating? Chassis & suspension diff?
ANSWER : The C/V version is rated for 1,500 pounds of cargo and 300 pounds of passengers (1,800 pounds combined). All other versions of this vehicle, including the SE, have a suspension rated for 1,150 pounds max, passengers and cargo combined. Obviously, if you take the seats out of an SE you will reach your minimum required payload of 1,200 pounds. To determine the exact load carrying capacity of a vehicle simple view the certification placard on the door pillar which will contain the GVWR (subtract curb weight to get cargo capacity) but note that ratings per axle which must be observed to avoid overloading and dangerous operating conditions.

Can a 2000 dodge caravan fuel injector wiring harness be used on a 1999 Dodge Caravan, engine being a 3.3L 6 cylinder flex fuel.
ANSWER : Hi there, thanks for writing in. To my knowledge, Dodge did not make significant changes from the 99 to 2000 Caravan 3.3 liter engine. However, with that being said, it’s hard to know for 100% certainty that the fuel injector control pressure sensors or wiring harness is compatible with both years.

The best way to verify this information before you purchase any parts is to contact one of our local professional mechanics to service your injector control pressure sensors and harness; which will allow our parts team to find an aftermarket part that will be correct for your 99 Caravan.

Can I put a 2007 dodge caravan engine in a 2001 Dodge Caravan
ANSWER : There were 4 different engines used in the 2007 Caravan. Looking at an example, namely the 3.3L (VIN "R") that was used in model year 2007, the head and block casting numbers of that engine do not match the engine used in any other model year of the Caravan. Inasmuch as the engine is controlled by the PCM, replacements these days have to be exact and must be interchangeable per the manufacturer catalog, otherwise the set-up (the swap) almost undoubtedly will not work and often won’t even "start". If you are trying to find a used engine or perhaps trying to find a harness for your 2007 Caravan, or any other vehicle, your best bet by far is to simply search the database at Car-Part.com and you will find an exact match for almost anything you might need. You can also perform interchange searches at that website to see all your options in terms of multiple model year or model applications. If you are interested in an engine replacement or a harness installation (OEM to OEM), YourMechanic professionals in certain locales can assist with that. Please simply inquire based on your locale. If you have further questions or concerns, do not hesitate to re-contact YourMechanic.

Starting issue in 1999 Dodge Grand Caravan
ANSWER : The first thing you want to do is find out what isn’t working. If you try to turn the key and nothing happens, and the starter isn’t turning over, then have the battery load tested. It could be a bad battery or it could be a bad starter. But if you try the starter and the engine makes a starting sound but it doesn’t start up, then it’s much more complicated.

I’ve got a video for that "fixing the car that cranks but won’t start up"–watch that. You’d want to check if the fuel pump is working, if you have fuel going into the fuel injectors, and if there are any massive vacuum leaks in the engine like big holes in the engine that sucks air. If you want to have a professional take a look, a certified technician can come to your home or office to inspect your car’s starting issue and determine what repairs are needed.
