2000 Dae Woo Lanos 1.5L keep getting a DTC Code


you will have to check the fuel injector for operation. then check for a vacuum leak where the intake mounts by cylinder 4, could also be a compression problem for that cylinder. an 02 sensor won`t cause a single cylinder misfire or fuel filter.

My 2007 dodge caravan is missing on the 3rd cylinder, I have replaced plugs, wires,coil pack and idel sensor and it is still not running right what could it be


i would check compression on that cylinder. you can rent the tool from some autopart stores. it just threads into the sparkplug hole and then crank the engine. check the guage and see if its within the same psi range as other cylinders.

My 96 nissian maxima turns off when driving down the road i try to turn the key ,lights in dash on horn blows but will not startcould it be alternater ,or what how does the 02 sensor go by functioning ...


As of 1996,all cars sold in the US were required to have an OBD-II computer interface port.
You may want to go to Advance Auto Parts, AutoZone, or Pep Boys, and get a free read
of the code(s) that you computer may be posting to help with your diagnosis.

The code coming from your vehicle's computer may be one or more of:


P0130 02 Sensor Circuit Malfunction (Bank I Sensor 1)
P0131 02 Sensor Circuit Low Voltage (Bank I Sensor I)
P0132 02 Sensor Circuit High Voltage (Bank I Sensor 1)

Maximas with the VE30DE and VQ30DE engines use a distributorless ignition system that is controlled by the Engine Control Module (ECM). The ECM receives a signal from the crankshaft sensor (the CPS - Crankshaft Position Sensor), and processes the signal based on inputs
from other various engine sensors, including the Oxygen sensor.
(this is the role of the O2 sensor in ECM operation).
Then the ECM sends signals to each of the individual coils in the proper firing order.
This system is more efficient than a distributor, and has fewer moving parts. The high voltage coils are directly attached to each spark plug, allowing a higher energy spark within the cylinder. A high energy spark means a faster, more thorough burning of the air/fuel mixture, which produces more power and lower emissions.


SECONDARY SPARK TEST - works for all cars, including Maxima.


1. Remove the spark plug.

2. Install the spark plug to the ignition coil/coil pack, then attach the coil wiring.

3. Ground the plug at a good ground location on the engine.

4. Crank the engine and check for spark.

5. If spark occurs, the ignition system is functioning properly.

6. If no spark exists, test the ignition coil/coil pack, power transistor and related wiring.

----------------------------------------------------------------------------------------------------------------------------
HEI Ignition Spark test - works for all cars, including Maxima.

The next level test you may want to try is a HEI (high energy ignition) spark tester kit. Cost is
about $30 at most auto parts stores. Harbor Freight Tools sells a chinese equivalent for about $16.
Place the spark tester on each of the spark plugs, and watch as the little light in the tester will
light up each time the spark plug is fired by the computer. You can actually see weak or
intermittent sparking as the motor runs - you can tell by the relative strength of the light as
you compare the intensity and duration of the light across all 6 cylinders.

If your problem were the alternator (or its built-in voltage regulator), your battery would not be
getting a proper charge, and you
wouldn't be able to start the car after a drive, since the battery would have been drained during the
drive - normally, the alternator will both charge the battery and run all electrical
features of the car during a drive.

To test your alternator, place your DMM (digital multimeter) across the battery terminals while the
car is running - it should read 13.5VDC to 14.5VDC. With the car off, you can test your battery
voltage with the same DMM - it should read 12.65 VDC (for a fully charged battery).

Alternatively, you can take your car to Advance Auto Parts, AutoZone, or Pep Boys, and they'll
attach their "charging system tester" to your car and give your car a nice test for free.
I do this with my customers' cars just to get that nifty printout of the problem. Its nice
to show a vehicle owner somethng in black & white when I'm recommending a new charging
or ignition system component (some of which can be a bit pricey).

I get engne code p0300 what does that mean and what do i do already changed plugs and wires


check the coil, Normally when that code comes up its followed by more, as in P0301 02 03 , which would indicate which cylinder is being effected, P0300 Random/Multiple Cylinder Misfire Detected is what the code means and any of these could effect that code being thrown
  • Faulty spark plugs or wires
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector(s)
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Stuck/blocked EGR valve / passages
  • Faulty camshaft position sensor
  • Defective computer

Only 3 cylinders work how much will it cost to repair


No way to tell until someone identifies why the 3rd cylinder isn't working. It could be something as simple as plug wires or a coil pack. It could be a Crank Position sensor being faulty. You just won't know until you do some testing. Do a compression check and see if you have good compression and eliminate valve and ring problems. If the compression is good replace the plugs and wires and work your way through the system.

I am trying to install a new lift gate support cylinder on the hatchback of an '02 outback. I cannot get the new cylinder to compress at all. Is there some way to get the brand new cylinder to compress...


That cylinder should compress but you will not be able to compress by hand theres a lot of pressure, but if you have it connected to hatch and doesnt compress then the cylinder is on wrong or bad.

My 5.3 02 silverado has low compression and is miss firing


Any engine that has low compression indicates worn internal parts. $$$$ The usual suspects are worn piston rings. Have you checked all 8 cylinders? If so, are they all losing compression, or just certain cylinders? If you have access to a garage, do a compression check on all 8, you may also want to get a cylinder leakdown test, again, on all 8 cylinders. You can then decide what course of action would be best. Good Luch!

Need compression settings,black smoke out of tailpipe too


Rather then actual pressures, it is better that all cylinders be within the same ballpark of each other. If 5 cylinders are around 180 lbs. of pressure and one cylinder is 140, that would indicate a problem. Perhaps you could take you vehicle to one of the major auto parts stores and have them check to see if there are stored trouble codes which might indicate whether the O2 sensor is the problem before replacing it. This is usually a free service.
