Oguz common good days . Voyager 2001 model 2.4L cars in the cylinder head has been replaced as a result of the TPS failure has occurred . TPS has been changed but continues to malfunction. may wonder why . is goingwrong in theprocess from a cylinder head or any electrical Waiting for your urgent response

If you have the 2.2L 4 cylinder engine, and the vehicle has more than 50000 miles, the most like problem would be a failure of the timing chain tensioner. This is a known problem and commonly occurs. Problem is, if it happens at highway speed, chances are you are going to have to replace the timing gear set, chain, tensioner, and the cylinder head as there will be bent valves. The only way to avoid this is to replace the timing chain tensioner every 50K miles or get rid of the car.

waterpump failure.. thermostat stuck, bad cooling fan(s) or relay..repost..

Most common problems are external coolant leaks (resulting in low coolant level), failed thermostat, blocked radiator (external or internal), electric fan not coming on, clutch fan inoperative. Other causes less frequent are: improper coolant/water concentration (should be 50/50), head gasket failure, transmission slipping or engine running excessively lean or a bad pressure cap.
One thing certain though....repeated overheat and continued driving in overheat condition will result in an expensive failure (blown head gasket, cracked cylinder head or crank bearing damage).
Carefully check each item I've listed and correct whatever it is you find, then resume using the vehicle.

If its just condensation in the oil cap or dipstick, to some degree its normal. However if you have water in the oil and its very creamy in texture, its probably a head gasket leak, or cracked head. Its important to get it repaired soon, or total engine bearing failure will result.

Chrysler did not have a 3.4L engine, your 2000 could have a 2.4L 4 cylinder or a 3.0L 6 cylinder engine, both engine's are INTERFERENCE ENGINE'S, which in the event of timing belt failure, piston to valve damage will occur, the cylinder head will have to be remove to replace bent valve's, with bent valve's engine will not start, due to no cylinder compression.

Strange that it failed the emission test. The codes given relate to the transmission computer not outputting the correct signals to the engine (power) control module ECU. Have you noticed any abrupt gear shifts lately? I wonder if the emission test failure is related. Sometimes the gear selection failure can be as result of the ECU getting the incorrect information from a faulty throttle position sensor TPS. The ECU relays the information to the transmission controller and this snatches at the gear shift at slightly the wrong time. A faulty TPS might also be responsible for the ECU setting the wrong fuel air mixture and this would result in inappropriate exhaust gas emission. The TPS is on the throttle plate shaft and is located on the outside of the throttle body. The two outer pins on the TPS plug have 0 volts and 5 volts. The middle pin sends the voltage to the ECU according to the throttle shaft position between 0 to 5 volts. Check out the TPS thoroughly before looking for something more complicated. Then next I would pull the sockets from the respective control units and make sure all the contact pins are clean and bright to ensure good inter connection

Blown head gasket for sure if its a petrol engine.

If its diesel then its overfuelling.

12 is battery disconnected lately, or dead. No worries.
13 & 14 are your likely problem, M.A.P. sensor.
52 is oxygen sensor.
I would replace M.A.P sensor, disconnect battery for a few minutes to erase codes, then hook-up start & run the vehicle for a while. My guess is that the oxygen sensor is being tripped by Map sensor. Run for a couple of days if running o.k. then check codes again.

The cylinder head is a crucial part of all combustion engines, and cylinder head cracking can result in catastrophic damage to the engine. In some cases, cylinder head cracking may result in such severe injury to the engine that it must be replaced. As a result, most motorists try to prevent cylinder head cracking, as an ounce of prevention in this case is worth many pounds of cure. The causes of cylinder head cracking are all relatively simple and easy to prevent, except in the case of mechanical parts failure through no fault of the operator. The cylinder head, used in combination with a head gasket, seals the cylinders of the car, along with other parts associated with them. The cylinder head is customized for the vehicle, and has very precisely milled surfaces to provide a smooth and flush fit with all connecting parts. In the case of a minor crack, the cylinders may lose compression and misfire. Major cracks can cause severe damage to the cylinders of the engine. For this reason, when replacing either the cylinder head or the head gasket, make sure that you are using the correct parts, including bolts, for the job. Even a brand new car can experience cylinder head cracking if parts have been installed incorrectly or if there are weaknesses in the metal. Especially in the case of a vehicle which is still under warranty, drivers should contest the cylinder head cracking with the dealer. Be certain to inspect any vehicle before you purchase to check for weak spots in the metal or incorrectly installed components. This includes the cylinder head gasket, because improper installation of this vital part can cause cylinder head cracking. Cylinder head cracking has become more common as car manufacturers use mixed metals in their engines. Many vehicles, for example, have a solid cast iron engine block but an aluminum cylinder head. These two metals expand at different rates, and this can lead to cylinder head cracking. The most common cause of cylinder head cracking is overheating. When a vehicle overheats, it puts stress on all of its metal components, including the cylinder head, which is often at the center of the heat. This can cause the head gasket to fail, which may lead to cylinder head cracking as the components warp and pressure begins to leak. All drivers should properly maintain their vehicles to prevent overheating. Many drivers mistakenly pour cool water into the radiator when their vehicles overheat, in an attempt to bring the temperature down. This is not a good idea, because the rapid temperature change will cause cylinder head cracking due to thermal stress. In a case where the cylinder head survives overheating, the driver may inadvertently destroy it by trying to do good. To prevent overheating, make sure that your radiator is filled and in good condition, with a tightly sealed cap. Check to be certain that your engine thermostat is in good working order, and accurately reflecting the temperature. Make sure that you have no leaky belts or stretched hoses, and that the fan is working effectively. If your car does overheat, stop, turn off the engine, and allow it to cool completely before adding water. Cylinder head cracking can also be caused by localized hot spots in the engine, which usually represent a failure in some portion of the cooling system. Always make sure that hot spots are addressed, particularly if your head gasket has failed and required replacement recently. Hot spots are often caused by uneven expansion of engine parts, leaky hoses, and pre-ignition in the cylinders of the engine. If your car has overheated, check the cylinder head and gasket for signs of cracking or warping. If the cylinder head has warped even slightly out a flush state, it will cause cylinder head cracking. In this case, the head gasket may need to be replaced and the cylinder head should be ground even again before it cracks. Thanks for using FiXya - a FiXya rating is appreciated!

My 98 Grand Voyager 3.3L engine # is located on the rear of the cylinder block, below the cylinder head, your 99 should be the same location. It contains the last digit of the model year, manufacturing plant, engine, usage (car, truck), month/day, serial code (last 8 digits of vin). countrycurt0
