SOURCE: High Idle and Torque Converter wont lock in all the time

i would check the iac valve on all three of your vehicles and on the ones that are sticking and wont idle down i would also verify that the throttle plate in your throttle body is not hanging up on a bur or something.

SOURCE: 86 port FI, open loop (cold) runs great, hot

try the "tap test" on the ecm. After closed loop,just lightly tap on the computer,you may see it change or stall.Mine did that and the ecm was bad.

SOURCE: B0012 SAYS FRONTAL PASSENGER DEPLOYMENT LOOP. WHAT

B0012 is a fault on the DRIVERS side, you sure you read the code right?
If it is a B0012 then any of the wiring could be suspect the coil or the air bag it's self. I have seen a couple of cars coming with this code and I found the wires coming out of the air bag in the steering wheel to be rubing where they go through the steering wheel into the colume, may want to check there first.
Report back if the code is something else so we can try and assist you.

Cause
The most likely cause of any one of the following DTCs: B0013, B0014, B0017, B0018, B0024, B0026, B0043, B0044 is improper connection/high resistance in the IP harness to inflatable restraint module connector C221 and/or C222.

Diagnostic Information
DTC B0013, B0014, B0017, B0018, B0024, B0026, B0043, B0044 will set when one of the following conditions occur:
• The SDM detects the air bag module deployment loop resistance is greater than 4.8 ohms for 500 milliseconds.
• The SDM detects that the voltage at the air bag module high control is less than 2.4 volts and deployment loop resistance is 6 ohms or greater for 500 milliseconds.
• For additional diagnostic information, refer to DTC B0013, B0014, B0017, B0018, B0024, B0026, B0043, B0044 in the appropriate SI Document.

Why is my check engine light coming back on after ive alredy replaced o2 sensor (bank 1)?


The oxygen sensor regulates the fuel mixture, coming into the combustion chamber for combustion" The computer takes its cues from the O2 sensor and responds by changing the fuel mixture. This produces a corresponding change in the O2 sensor reading. A bad coolant sensor can also prevent the system from going into closed loop because the computer also considers engine coolant temperature when deciding whether or not to go into closed loop. i believe the coolant temperature sensor is faulty.have it change so that the system will be close loop.

Why does my2004 gmc envoy xl slt idle high at startup?


This is normal. All vehicles idle high at start up to get the engine to operating temperature. This is known as open loop. The computer ignores signals from O2 sensors to keep your engine running safely. Once it has warmed up, it will enter closed loop, and you will see a decrease in idle.

Fouls plugs after 50-55mph


its rich, (which engine, there are more than 1) ?????
and is not in closed loop mode (ECU) fix that first.
so diagnose rich.
EFI engines. no country stated, as others have carbs way newer,.
1: too high fuel pressure, (gage it) alldata.com has spec. and steps.
2: injector(s) leak. same tool above finds this, ask.
3: ECT reads low temp all time time, (thermostat bad, or missing?)
4: IAT reads too low. (TBI engines, with MAP sensors)
5: 02 sensors bad. (if all else is good and o2 reads wrong its bad)
6: exhaust leaks near, 02, causing o2 to read lean, forcing max rich.
7: did you run the ECU scan codes? the Check engine flashing light using the diagnostic jumper , yet?

mostly those. there are tests for each. ASE ways and means.

if your swift has a heated 02 sensor, it can even hold closed loop
at idle..... sure can, and if so , i check that first.
then closed loop at 2500 rpm , in neutral. (how is complex)
on these old dogs. suz, the worst ,no scan tools. are sold over the counter. so I must use a scope.
i watch the 02 sensors output. and make sure engine goes to closed
loop, if not i fix that. first.
there are ways to do this, (by me forcing lean or rich using other tricks of the trade. ask. I do so , to see if i can wake up the o2 sensor.
this is all covered in ASE courses...... this magic./

id be all over, fuel pressures, REAL not guessing or squirting checks bs.
id be all over exhaust leaks near the O2.
and first a new 02. most cars, its like long ago ,dead and you
look and the tip is , GONE! 1992 oxy sensors are useless.

I have a 89 buick electra 98000 miles I failed emissions for high co at idle I put a obd1 tester on it it showed vehicle was not going into closed loop I replaced oxygen sensor it then went into closed...


to stay in close loop o2 sensor have to be hot
and the converter catalyst is the one who keep the heat......
converter is it factory or never been change.
with scanner obd1 you should see the voltage variation of o2 sensor. it should go from lean to rich . .500mv is the middle then under .500mv is lean and over it is rich.......with this information ecm correct the fuel delivery
hope it helps

My Pilot's Check Engine Light is on and it gives a P2279 code when I check it. I have replaced the intake manifold gaskets and the injector base gaskets, but that hasn't worked. What else can I do?


Got 100k miles on it? ever run crappy fuel additives that can wreck a good 02 sensor?
LOTS ! if motivated. (are you asking for wild guessing?)
what engine size?
first off read the FSM , for your car and year. it covers this DTC.
P2279 intake leaks or PCV. it stated on 0bd2 scan code pages.
but in the FSM , there is far more, why not read that..???
it tells you the conditions before the test, and what it measure.
both are big clues to why?
the freeze frame , you didth post that,, it tells you all conditions
related to 2279, at the instant of failure.
1: speed, rpm,. and load.
2: in closed loop:
3: sensor reading an the one that was wrong.
you dont have a real scan tool or just useless code reader?

with the freeze frame in hand, id drive and log data.
my scan tool (scantool.net and palmer software) $200? investment. (paid back zillion times?)
i can log scan, driving and see all condition during the drive
before and after the 2279 (im assuming you reset it and it repeats per OBD2 protocols.)

my first test are like this.
1: engine warms fast to over 180F and holds. ECT reading, PIDS.
PIDS are live data from sensors. in full view
2: as it warms, parked, at idle my engine goes to closed loop real fast (by virtue of 02 heaters )
3: my engine is now 100% hot and fully warm and it idle
its in closed loop and the LTFT is at -4%
not -40 nor +40
the natural engine tune is 4%rich closed loop sucks out -4% to reach STOICH) if not a new 02 sensor at 100k miles. all this is whistling in the dark, if the 02 fibs and reads rich for STOICH
then it goes lean, or in your case, the O2 Fibs(old or poised)
the 02 reads lean and had to add tons of fuel to correct it.
i dont have a 2005 fFS to see 2279.
it will flat say something like, +35% LTFT (lean) trips 2279s.
my guess, is that 2279 is what I call the LTFT (rail fail)
all newer OBD2 cars have this RAIL fail trips
the EFI can control +(-) 40% more more, but over a lower number range it trips too rich or too lean , as an early warning.

I watch CLOSED loop like hawk , idling hot and med. speed driving hot engine, no hills. steady right foot , be darn sure
that CLOSE LOOP holds there?
if not fix idle CL bad first.
if not fix cruise CL bad next.

IMO , at 100k why not put in $20 O2 sensor, (ask for sources)
or splurge and buy the PNP BOSCH, at any store, just front sensor, not rear. (pnp is plug-n-play) just plugs in , no wiring as in my $20 cheap skate ways.

a bad PCV can be blocked, or stuck wide open.
or the PCV hose cracked sucking in lots of oxygen (illegal oxy btw on the vac side)
the PCV meters , (checkvalve and orifice) piston ring gasses (bypassed from the rings , products of combustion) so no air leaks or bad valve is allowed or idle air mix can be wrong.)
PCV can fail 3 ways, jammed check valve. stuck open, or air leaks. (all have bad consensuses, jammed causes oil leaks.)

many times, we get lean at idle, and can not find the air leak.
(shows a +30% LTFT)( long term fuel trim (trend))
and out comes the smoke machine, (great skills need to use it.
as some leaks are normal and others not, very hard)

i hope this helps. you. and others,

Code P2187 on 2008 Suzuki Forenza


DTC P2187: Fuel Trim System Lean at Idle

Fuel Trim Description
The Engine Control Module (ECM) controls the air/fuel metering system in order to provide the best possible combination of driveability, fuel economy and emission control. Fuel delivery is controlled differently during Open and Closed Loop. During Open Loop, the ECM determines fuel delivery based on sensor signals without Heated Oxygen Sensor (HO2S) input. During Closed Loop, the HO2S inputs are added and used by the ECM to calculate short and long term fuel trim fuel delivery adjustments. If the HO2S indicate a lean condition, fuel trim values will be above 0%. If the Heated Oxygen Sensors (HO2S) indicate a rich condition, fuel trim values will be below 0%. Short term fuel trim values change rapidly in response to the HO2S signals. Long term fuel trim makes coarse adjustments in order to maintain an air/fuel ratio of 14.7 : 1.

This code can only set when the engine control is in Closed Loop. The engine must be fully warmed up.

This must be diagnosed using a scan tool that can read engine data in order to determine the actual cause of the problem. It can be caused by the following things:

> Vacuum leaks
> Malfunctioning, dirty, or skewed Mass Airflow Sensor (MAF)
> Malfunctioning or skewed Manifold Absolute Pressure Sensor (MAP)
> Dirty or sticking injectors
> Malfunctioning or improperly programmed Powertrain Control Module (PCM)

I have a 1997 rav4..4cyl stalls when taking off from a stop.i have a scan tool.at idle engine load % is 30-40..tps % 19 no codes.happens more when cold ant turning.it stalled today, and rolling nuetral...


Since you are not getting any codes , I think your problem may be in the fuel system.Have you checked the fuel pressure / regulator? Or any voltage drop in the system.

ECM switches from closed loop to open loop at idle after warmup


WHEN ENGINE GOES CLOSED LOOP TO OPEN LOOP.YOU HAVE A RICH FUEL MIXTURE.YOU HAVE A VACUUM LEAK.BY YOU HAVING ROUGH IDLING.AND A HIGH MILEAGE ENGINE I WOULD DO A COMPRESSION TEST OR CYLINDER LEAK DOWN. CHECK FOR LEAKING VALVES AND LOW COMPRESSION .THEY BOTH WILL CAUSE ENGINE TO IDLE ROUGH CAUSE MISFIRE.CAUSE OPEN LOOP CONTAMINATE HO2 SENSOR CAUSE A RICH FUEL MIXTURE.

P0125 obd code


P0125 Insufficient Coolant Temperature for Closed Loop Fuel Control
This means that the engine coolant temperature (ECT) sensor indicates that the engine
has not reached the required temperature level to enter closed-loop operation within a specified amount of time after starting the engine.

A code P0125 may mean that one or more of the following has happened:
  • Insufficient warm up time
  • Low engine coolant level
  • Leaking or stuck open thermostat
  • Faulty coolant temperature sensor

The simplest thing to do is to reset the code and see if it comes back.
If the code comes back, the problem is likely going to be the result of the above causes (faulty thermostat, faulty coolant sensor, or a low coolant level).
