Hey guys so I was Driving down the road to work and all of a sudden I lost power I felt a little tiny click on the clutch pedal about a block before but i didnt really think much of it... When I was pushing on the gas I was watching my boost gauge... ( I dont have a turbo set up.. ran outta funds but I have the gauges still hooked up which def help in these situations!) so anyway I would push the gas and it was almost like it was starving for air maybe even gas I cant really tell all I know is that the vacum only went up to -15 which should be at 0 at full throttle hence no boost....

Now the only thing Ive done was yesterday I changed the oil Ive changed oil before so this was no big deal checked the filter made sure I got the right one ... levels are good....

I am getting a service engine soon light too.....

Any suggestions So I can service the engine soon??? The dealership sucks btw they dont know... they said because I have the vacume lined tapped they cant figure it out.... all it is, is a stupid fn T connection to a gauge.... my god does it REALLy make it that more complicated! LOL and my Air/fuel is tapped off the Fuse box...

so any help would be GREAT!

Thanks!

 

you have a cel - pull the code

 

+1, just pull the code and go from there. let us know what you come up with.

 

+1, what code...

 

jinx

 

Ill try to find some time tonight after work to pull the code

 

Ok Guys Im throwing a
P0401- EGR
P2138-TPS/Pedal Position Sensor/SwitchD/E voltage Correlation

 

Here are the mitsu codes and definitions, and some information to help you diagnose the problem. sounds like your egr valve is sticking, the aps is messed up, or the ecm/pcm is going bad. any of these three things could cause both codes, directly or indirectly.

P2138 Accelerator pedal position sensor (main and sub) range/performance problem

P0401 Exhaust gas recirculation flow insufficient detected

EGR

ECM <M/T> or PCM <A/T>
monitors the operation of EGR
system by the pressure difference
of intake manifold between before
and after introduction of EGR using
the manifold absolute pressure
sensor

TECHNICAL DESCRIPTION
• When the EGR valve (stepper motor) is actuated
from the fully closed position toward the open
position while the engine is running, EGR gas
flows.
• The ECM <M/T> or PCM <A/T> checks how the
EGR gas flow signal changes.
.
DESCRIPTIONS OF MONITOR METHODS
Small manifold pressure change during exhaust gas
recirculation (EGR) operation from closed to
open.
.
MONITOR EXECUTION
Continuous
.
MONITOR EXECUTION CONDITIONS (Other
monitor and Sensor)
Other Monitor (There is no temporary DTC stored
in memory for the item monitored below)
• EGR stepper motor monitor
Sensor (The sensor below is determined to be
normal)
• Mass airflow sensor
• Engine coolant temperature sensor
• Intake air temperature sensor
• Barometric pressure sensor
• Throttle position sensor
• Accelerator pedal position sensor
• Manifold absolute pressure sensor

TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are: )
• Contaminated EGR valve and EGR passage.
• EGR valve (stopper motor) failed.
• Open or shorted EGR valve (stopper motor) circuit,
or connector damage.
• Manifold absolute pressure sensor failed.
• ECM failed. <M/T>
• PCM failed. <A/T>

ACCEL

CIRCUIT OPERATION
• A 5-volt power supply is applied on the accelera-
tor pedal position sensor (main) power terminal
(terminal No. 2) from the ECM <M/T> or PCM
<A/T> (terminal No. 92).
The ground terminal (terminal No. 1) is grounded
with ECM <M/T> or PCM <A/T> (terminal No.
91).
• When the accelerator pedal is moved from the
idle position to the fully opened position, the
resistance between the accelerator pedal position
sensor (main) output terminal (terminal No. 3)
and ground terminal will increase according to
the rotation.

CIRCUIT OPERATION
• A 5-volt power supply is applied on the accelera-
tor pedal position sensor (sub) power terminal
(terminal No. 8) from the ECM <M/T> or PCM
<A/T> (terminal No. 97).
The ground terminal (terminal No. 7) is grounded
with ECM <M/T> or PCM <A/T> (terminal No.
96).
• When the accelerator pedal is moved from the
idle position to the fully opened position, the
resistance between the accelerator pedal position
sensor (sub) output terminal (terminal No. 6) and
ground terminal will increase according to the
rotation.

• Output voltage is between 0.335 and 0.935 volts when
foot is released from accelerator pedal.
• Output voltage is 4.0 volts or higher when accelerator
pedal is fully depressed.

 

the pedal out of range is a known issue and there is a reflash for it.

 

I'm leaning toward the 2138 code then. it would cause not only the code itself but the EGR system is dependant upon the tps reading being accurate.(see above information) the TSB on the reflash should make them do it under warranty, regardless of mileage, and the other information I have posted for you should get you any other answers you need. if you need more help ask more questions, but remember we need enough information to answer you so make sure you tell us everything you find

 

did the dealership not pull the codes? I have the same book they have, and they should have been able to trouble shoot the DTC's pretty easily. sounds like they just didn't want to deal with it. Tell them you've already read the Magnuson-Moss Warranty Act, but actually read it too. It protects your rights as a consumer.

 

I always get that biznicht code before my cat one, the car feels like it just came out the closet.... somehow it always corrects itself later on the day

 

I did the hand pump vacum test from the FSM according to that the EGR is broken.... does anyone know where I can get one at a REASONABLE price?

 

car-parts.com

the egr valve is part of the emissions system, covered by federal law for 80k IIRC. the dealer should replace it under warranty. search for federal emissions warranty, and be sure to read the warranty act. unless it's your fault it's their problem.

also, you can try and see if cleaning the EGR will help, you wouldn't believe how often you can save yourself some money like that.

 

The 2138 code will definitely put your car into limp mode.

Does anybody have the specific info for the TSD (number, date, etc)? I want that info before I consider bringing this up to the dealership and there's no info on the TSB on the NHTSA's site.
