Question about 1987 Plymouth Caravelle

1 Answer

I need a manual for an 87 Plymouth Caravelle. I need to replace the oxygen sensor to pass emissions testing and I'm trying to do it myself. It seems pretty easy but I need to figure out exactly where the oxygen sensor is located.

Just follow your exhaust manifold from engine to where it connects to exhaust pipe. It should be right above that, threaded in to exhaust manifold.

mccartlidge. are you serious?? high HC is the result of a headgasket problem??? do everyone a favor and dont give advice when you clearly dont know a damned thing about emissions. as far as solutions to your high HC output, someone else mentioned the possibility of a worn out cat along with carb problems and or a simple air fuel adjustment. this car if i remember correctly has a feedback carb which means it has an oxygen sensor and a mixture control solenoid on the car to fine tune the air fuel mixture. it is not uncommon to have a oxygen sensor not functioning at all or out of normal calibrated range. easy test for oxygen sensor(single wire oxygen sensor ) is to hook up a voltmeter at 0 to 1 volt range(positive lead to oxygen sensor wire, negative lead to any good ground source) and watch the voltage. a perfectly working system the signal should look like a wave constantly rising and falling from .9v-.1v. test at 2500 rpm as well as at idle on a hot engine.if the oxygen sensor doesnt rise and fall, add fuel(spray small amount of carb spray) into carb while at idle or high rpm and the oxyen sensor should go full rich(approx .8-1v) that is point 8(.8v) not eight volts. you will usually see a reading of .9v . if the oxygen sensor doesnt put out a rich reading than its no good. on the other end you can remove a vacuum line(brake booster hose, half way removed as to not stall the engine) the oxygen sensor should go lean which means around .1 volts. if the oxygen sensor does not respond correctly replace it. beyond that, the engine first and foremost has to run on all cylinders to run clean and efficient. if it has a missfire or dead hole that will cause high HC along with high CO as unburnt fuel is going out the tail pipe. i could go on and on about possibilities but figured i would give you a couple basics to go on. Good luck.

My 87 voyager won't pass emissions test.. I put complete tune up and oil change on it after it failed. Now the inspections place said it made it worst. I know the belt to my air pump is in bad shape ,...

You change oxygen sensors? thoses are now considered part of of tuneup on high mileage engines,plus if you drive highway for 30-49 miles before going gettting emissions testing you get better results.

The vehicle does not pass the emission test dew to the oxygen sensor of bank 1 defective

they are inexpensive (usually less than $75, some are less than $40) and fairly easy to replace (might need a special socket, available at all auto parts stores and less than $15)-you probably have a 'lazy' sensor, that is it does not switch fast enough to satisfy the engine computer, most O2 sensors need to be replaced at 100,000 miles but are not until they throw a code.

I have just bought a 1990 Plymouth Voyager. She is in a great condition - regularly maintain, new transmission, no oil leaks/rust or using of coolant. She drives perfectly, however the 'check engine'...

If the fluids are ok, the check engine light is most probably telling you to replace the Oxygen Sensor. Unless you live in a big city and have to pass emissions testing, you can generally ignore this. The Oxygen Sensor is probably carboned-up and may result in the engine running a little bit rich.

Here is a link to a page that will tell you how to have your car tell you what is wrong with it! The check engine light can flash out the fault codes for you.

Enjoy, good luck, and happy holidays!

My service engine light came on and when tested it came up as the heated oxegen sensor.. how important, and what time frame do i have before it is critical?

the heater just gets the oxygen sensor working as soon as possible, the quicker it works, the quicker it controls the engine, so it affects emissions and mileage. You can put it off, but it needs to be fixed.

When all the monitors have run their tests then it will pass emmissions providing that your repairs were successfull...You need to drive it for at least 75 miles so that it can complete its tests....

'87 Plymouth Caravelle vacuum hoses crumbled.

in 1987 hoses were not hard when new
harden and perish due to heat in engine bay and age

I dont think you can buy hoses as a kit
but worth ringing a plymoth Caravelle parts supplier

you can buy silicone or standard rubber hose

replace one hose at a time and take pictures of the hose joins
don't pull the lot off in one go and have a mess

cheapest way to replace all vacuum hoses is buy the hosing in lengths and sizes required from an auto parts shop

Improper fuel combustion; need to pass emissions test

Sounds like you need to replace your oxygen sensors.  If you have a four cylinder I think you only have one oxygen sensor and the six cylinder I know has 2.  You can check that out at your local parts store.  Anyway, the oxygen sensor helps the computers in your car make sure that you are getting the correct amount of fuel and air during combustion thus controlling your emissions.  I would think that if you haven't replace these in a while that is what is probably keeping you from passing your test.  Change the oxygen sensors and put a bottle of good fuel injector cleaner in a full tank of gas and you should be good to go.  I would suggest Greased Lightening fuel injector cleaner that can be purchased at Napa and O'Reilley Auto Parts.  Let me know if you have any other questions.  Thanks for an honest rating and for using FixYa!
