Question about 2002 Mitsubishi Galant

Open Question

02 Mitsu Galant dies at stops

We've recently replaced the bank 2 sensor 2 O2 Sensor. We also had all the spark plugs and wires changed.

For a long time now the car has had a problem of re-learning to idle correctly after the battery was disconnected, but now I think it's more than that. After the service, the car was running great for weeks, but I've noticed that when it rains, their's a squeeling belt, and after you drive for a few miles, the car begins to shutter and the rpm's drop when you come to idle. After a bit, it dies alltogether. The belt only squeels if the wether is wet, and so far as I can tell, the car is only dying in the same circumstances. Any ideas ?

Im pretty sure the bank 2 is talking about by the catalitic converter and since is sensor 1 it should be before the CAT otherwise it should be on the exahust manifold prolly in the back of the engine.

Sounds like the EGR valve is bad and is stuck in the open position.Just replace that and you should also check the catalytic converter.

SOURCE: The car runs perfect, but dies at idle.

remove & clean your IAC motor & see if that doesn't help. If it cures it for a while then does it again, replace it.

2003 honda civic o2 how to replace And how do i fin out which once is it

Hi Jesus, Im AL the owner of Big As Auto Repair.

If you have a 4 cylinder engine then you will only have two 02 sensors 1/1 is upstream and 1/2 is downstream. Upstream is the one closet to the engine and downstream is the one farther away from the engine.

If you have a six OR eight cylinder engine you will have four 02 Sensors. 1/1 means Bank One Sensor One. 1/1 and Bank one means right bank and right bank means the side with the number 1 spark plug. SO, 1/1 means, "Right Bank" Upstream 02 sensor. 1/2 means, "Right Bank" Downstream 02 sensor.

2/1 means, "Left Bank" Upstream 02 sensor and 2/2 means, "Left Bank" Downstream 02 sensor. Hope this helps and please visit my auto-repair-website at:

The Galant has 4 O2 sensors before the Cat. The trouble code says P0031 Front. Any way to determine which sensor needs to be replaced?

If your car has 4 O2 sensors I will assume it is the V-6 model. Code Po031 is bank one sensor one. Bank one is usually on the side with spark plug #1 and sensor one is the sensor closest to the engine.
You could clear the codes and disconnect that sensor and see if it sets the same code to make sure.

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).

When at stop or idle it idles rough or dies engine light stays on and comes up bank 1 and 2 lean can you help thanks.

wiil try to help. if you've had it code read and it comes up bank one or bank two. this indicates a bad o2 sensor, it may even be both, you should have 2 o2 sensors,depending on engine size,will say you have a v6 possible. then only 2 o2 sensors located in the exhaust system,behind the exhaust manifold,in other words,on the back side of motor but before the catalytac convertor. look for wires that are green that lead to the exhaust system just before the convertor[a sheilded ]looks like a muffler, replace those and codes should go away. be sure after you replace those o2 sensors,you reset yor computer by simply disconnecting positive cable from battery to let the cars computer to adapt them into the sysytem. sounds difficult,but if you are mechanically inclined,you can do. use jack stands first,you will have to go underneath the car!! you will need a special tool that you can buy at parts store for around $20.00 to remove the 02 sensors. they will have to be unplugged elictrically, a push in tab will release the plug from sensor. the special tool to remove the 02 sensor will be a socket with a slot in it to allow the wire on sensor to slide into the socket,rotate the socket counter clockwise,the 02 sensor will screw out, replace each one and be sure to plug those back in. then resest your cars computer to allow the computer to adapt them to the system. hope this helps and thank you for choosing

O2 sensor bank1 sensor 1

usually bank 1 sensor one is closest to the motor(guess) but you can look it up in a manual and just changing the 02 sensor is gonna fix it they are anywhere from 40 to 100 dollars hope it helps

2004 Chevy Blazer O2 Sensor

there are two 02 sensors actually on the engine. bank one is cylinders 1 3 5 bank 2 is 2 4 6. it controls the fuel to air ratio, if the O2 sensor is not working, the engine goes into limp mode, which means it is just putting as much fuel as possible into the cylinder, which will effect your gas mileage.

The O2 sensor may be fine, the pigtails off the 02 sensor go bad, the connection. I had in my car, i change the 02 sensor twice, then I found someone said the pigtails may be bad, so I cut the cars wiring harness pigtail, and the one coming off the 02 sensor, and directly wired it with the original truck 02 sensor, and it worked. all 02 sensors look similar, they screw in the side of the engine, and just have 4 wires coming off of it.

Try your origional one, and just bypassing the original wire connector, what I did was cut it off, skinned the wires, put some heat shrink rap on it, combined the wires together soldered them together, and heated the wire shrink rap, so that way it is water proof. car works perfect now.
