there are 2 ports one for low pressure and one for high pressure. the low pressure is bigger in diameter and is usually close to the dryer and or fender and firewall. the high pressure is near the condensor on the fron of the vehicle. if there are caps for the ports low will be blue and high will be red. low side pressure should be 35-50 psi and high pressure should be 135-150 psi

1998/99 Dodge Dakota clutch and manual transmission problems

I've looked at two Dodge Dakota 4 cylinder trucks with manual transmissions. The first one had a clutch that slipped so badly it couldn't even pull away in first gear. It had done 75k miles. On the second truck, the clutch bit right at the top of the pedal travel. It didn't slip when being driven, though, and it shifted normally. When stationary, it was difficult to get the car into either first or second gear. The clutch wasn't dragging, though. The car had 116k on the clock. Are these types of problems common? Can the clutch be adjusted to bite lower on the pedal travel? Can the gear shift mechanism be adjusted in any way to engage first easier from stationary?

trouble code P0420 catalyst efficiency system

trouble code P0420 catalyst efficiency system below threshold what do i need to do to fix this problem

Answer

  • Most Helpful of 1 Answers

The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate. The downstream O2 sensor reading should be fairly steady. Typically the P0420 code triggers the Check Engine Light if the readings of the two sensors are similar. This is indicative of (among other things) a converter that is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions system.


Symptoms: You will likely not notice any drivability problems, although there may be symptoms.


Causes: A code P0420 may mean that one or more of the following has happened:
Leaded fuel was used where unleaded was called for
An oxygen sensor is not reading (functioning) properly
The engine coolant temperature sensor is not working properly
Damaged or leaking exhaust manifold / catalytic converter / exhaust pipe
Retarded spark timing
The oxygen sensors in front and behind the converter are reporting too similar of readings


Some suggested steps for troubleshooting a P0420 error code include:
* Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.
* Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).
* Inspect the downstream heated oxygen sensor (HO2), replace if necessary
* Replace the catalytic converter

One thing to note is that many vehicle manufacturers offer a longer warranty on emissions-related parts. So if you have a newer car but it's out of it's bumper-to-bumper warranty, there still may be warranty on this type of problem. Many manufacturers give a five year, unlimited mileage warranty on these items. It's worth checking into

Hope helps.

1998 Dodge Dakota Pickup Hesitates When Starting Then Stumbles

I own a 1998 3.9 L V6, Automatic Transmission Dodge Dakota, 2WD, 12 gallon fuel tank with 72,000 miles on it.

I drove two hours one day from my parents house to my own, parked it and when I went to start it the next day, it would only turn over and over.

The battery charge was fine, starter motor seemed to sound normal, engine would crank at normal speed (to the best of my knowledge). I couldn't figure out what had changed / failed.

So I looked at the three major components: Air, fuel, and spark. I could not get a spark (but I could smell fuel from the cylinder with the removed spark plug) so I tested the ignition coil for resistance and it checked out okay. I also attached a spark plug to the wire leading from the ignition coil and got sparks. From that information, I replaced the distributor cap, and rotor (the old ones looked okay as I did wires, cap, and rotor maintenance a year ago, but I figured it was worth a try). After doing so, the vehicle would start, but it hesitates and sometimes takes 5 to 15 seconds before it begins to run. Normally when the truck starts to fire, it stumbles until it reaches idling speed at which everything seems normal. I would say this happens 80% of the time. The other 20% the truck starts like it should.

Once running, I have no issues in performance, fuel mileage, or anything else that would make me think something was wrong. It's only when I start it and it's more relevant when the motor is warm and is started briefly after a quick stop (such as fueling up at a gas station, or running into a store for a gallon of milk).

Your help would be greatly appreciated.

98 dodge dakota slt 318. no heat, low operating temp

my truks fan runs continuously, the heater blows lukewarm air, the temp gauge does not rise at all, the lower and upper radiator hoses and radiator cap do not get hot. I am low on coolant. but i think my last mechanic has my owners manual so i am unsure to add coolant while cool or hot. why is my fan runninng constantly even though the engine is staying cold and if i am low on coolant shouldn't my engine heat up faster?

First thing first, turn off the engine wait for 15 - 20 mints, open the radiator cap and fill it up to the top then start the engine and see if it needs more water adn add as needed, then wait till you ca see the water circulating in the radiator now instead of corculating if it starts boiling out shut the engine replace the thermostat and do the whole thing again.

unless there is water in the engine the gauge will not be able to show the actual temp of the engine, so always malke sure you have water / antifreeze

98 dodge dakota oil pressure problems

I just bought a 98 dakota the guy i got it from said he hadnt driven the truck much in the last year and a half and has just been sitting around. I have had a lot of oil pressure problems. I completely lost it on my way home from getting it. had it towed and replaced the sending unit. This fixed the problem for about 30 min and lost all pressure again. I did an engine flush which seemed to help a lot. Now i only loose pressure when driving and turning higher rpms around 2800-3000+ rpms. I can be idleing and rev the engine higher and wont loose all pressure just slight decrease. I think it may be a sludge problem since it has been sitting for a while or the oil pump pick up screen may be clogged. Is there any way to clean the screen without pulling or lifting the engine??? I cant do it myself and dont have the money to send it to a garage or dealer to fix. Could i shove a wire or somethign up the oil pan drain and possible reach the screen? where does the screen sit inside the oil pan? Any answers or help would be greatly appreciated. Thanks

I personally would try pouring a bottle of Berryman's B-12 in the crankcase when it is warm and then changing the oil (which you have tried a similar approach with the flush). Or, I would add approx. 8 ounces of Sea Foam engine additive to the crankcase and drive it around for a little while to see if it helps. As a side note: You don't have to change the oil with the Sea Foam, only the B-12
