1999 suzuki grand vitara IM readiness incomplete

I replaced the " Y pipe and post converter, including the downstream O2 sensors. Now there are 3 incompletes for I/M readiness.

    I ran the drive cycle that was posted by Dave China, now it's showing only 2 incompletes. The one that is OK now was the O2 sensor monitor. The two left to solve are the catalyst mon and the evap mon. I'll keep ya'll informed. Thanks Dave!

G8D711S is not alarm system. This is Daytime Running Light module. You can pull out the connector, your front lights won't work when an engine start.

My GV 2002 has a Autostart AS1203 alarm system. There is a description on Internet.

SOURCE: 02 sensors not ready

The code P0420 indicates that the catalytic converter is not functioning efficiently. This could be because the cat is damaged or the engine is not running very well and the cat cannot keep up with the emissions. You should ensure that the spark plugs and ignition components are in top shape before replacing anything else. If a compression check reveals a low cylinder, you will not be able to prevent this code as even a new cat cannot keep up with a dead miss. If the state of tune and the compression is good, then you'll likely need a cat.

I've posted the drive cycle just so you know what to do when you have resolved the code.

  1. Cold Start. In order to be classified as a cold start the engine coolant temperature must be below 122°F (50°C) and within 11°F (6°C) of the ambient air temperature at startup.
    Do not leave the key in prior to the cold start or the heated oxygen sensor diagnostic may not run.
  2. Idle. The engine must be run for two and a half minutes with the air conditioner on and rear defroster on. The more electrical load you can apply the better. This will test the O2 heater, Passive Air, Purge "No Flow", Misfire, and - if closed loop is achieved- Fuel Trim.
  3. Accelerate. Turn off the air conditioner and all the other loads and apply half throttle until 55mph (88km/hr) is reached. During this time the Misfire, Fuel Trim, and Purge Flow diagnostics will be performed.
  4. Hold Steady Speed. Hold a steady speed of 55mph (88km/hr) for 3 minutes. During this time the O2 response, air Intrusive, EGR, Purge, Misfire, and Fuel Trim diagnostics will be performed.
  5. Decelerate. Let off the accelerator pedal. Do not shift, touch the brake or clutch. It is important to let the vehicle coast along gradually slowing down to 20 mph (32km/hr). During this time the EGR, Purge and Fuel Trim diagnostics will be performed.
  6. Accelerate. Accelerate at 3/4 throttle until 55-60mph (88-96 km/hr). This will perform the same diagnostics as in step 3.
  7. Hold Steady Speed. Hold a steady speed of 55mph (88km/hr) for five minutes. During this time, in addition to the diagnostics performed in step 4, the catalyst monitor diagnostics will be performed. If the catalyst is marginal or the battery has been disconnected, it may take 5 complete driving cycles to determine the state of the catalyst.
  8. Decelerate. This will perform the same diagnostics as in step 5. Again, don't press the clutch or brakes or shift gears.

Bank one stands for the same side as the number 1 cylinder. Sensor 1 is the first sensor in the bank, (closest to the engine or upstream).
In most cases you will find it on the drivers side\left hand side of the engine and above the catalytic converter. Look for it on the lower portion of the exhaust manifold.

The AF sensors are uupstream and the O2 down stream. The car' s computer tests them and it is saying your cats are bad. If you have a scan tool you could look at the data and see what the sensors are seeing. The Af sensors are the ones that control the fuel ratio in the car while the O2's just watch. AF's would be the one to change but there is no garuatee that the codes won't come back.

99 suzuki grand vitara o2 sensor bank 2 sensor 2 connector location


which engine there are 3,

G16, J20 and H25. 4 bank , 4bang, v6

all 02s have a connector about 1 foot from sensor. all.

my guess is you have the SOB, v6, it is a pistol

it looks like the engineer was asked, see if you can make it near impossible to change ! then make it the only connector on the

car with the lock , working backwards ! HE WON.



here is 1 page, just for this, issue, only one on the web. btw.

getting them off the hidden brackets, is no JOY

takes like an hour each.



enjoy

and do ask questions.

replace only the front, (unless smog man makes you do rear)

or you get P042x codes,.

I have a 2006 suzuki grand vitara,are the oxygen sensors the same in either bank of the engine?


Well, the upstream sensors are the same and the downstream are the same - so it takes two of each.
For the record you should never have to replace more than one or two sensors at one time. And trouble codes do not tell you the sensors have failed.

Relaced all that and didn't check the catalitic converter. When you get codes for MAF sensor and 02 Sensors, the first place to check is vacuum leaks, if none are found then it would go right to the catalitic converter. You might want to consider another mechanic.

Where are all three o2 censors in a 1999 s10 blazer. 4 door V6 engine and 4x4


The upstream O2 sensors will be before the catalytic converter just down from where the exhaust pipe(s) attache to the exhaust manifold. The downstream O2 will be right after the catalytic converter. Once you crawl under the vehicle they will be pretty obvious where they are in the exhaust pipe.

Where is the oxygen sensor located on a 2000 grand vitara


There are 3 different engines available in that vehicle, and the location of the O2 sensors vary depending on which engine you have. The sensors are before and after the catalytic converter in the exhaust system. So the best way to find them is to find the catalytic converter and find the little plugs, which have wires on them, screwed into the exhaust pipe in front of and behind the converter. If you have the 2.7L V6 you will find that you have two converters which are bolted directly to the exhaust manifold and hence there are 4 sensors.

Catalyst system efficiency below threshhold bank 2


before replacing cat converter replace o2 sensors, they go bad and give a false reading that cat efficiency is below threshold ,meaning converter is no good , i would replace o2 sensors and reset engine light and go from there,the o2 s are normaly the problem, unless you hear cat rattling, well good luck,

Replace oxygen sensors


these engines have 1 upstream o2 sensor and 1 downstream o2 sensor..the 1 in the rear exhaust manifold is the upstream and the 1 after the converter is the downstream..make sure you replaced the right one
