dont take soo much in consideration after you have make all this things, some time is on only for any wire faulty, or a shrt electrical arc in any place in wire system. ask auto tap mechsnics for this maybe they have similar case before.

SOURCE: code P2A00 what does this mean. service engine

The code indicates a problem with Air/Fuel mixture, and it is very possible with the "chips" you installed, the A/F ratio the ECM sees is out of tolerance. As far as inspections is concerned, you may need to remove the chips and reset the ECM before you go for inspection.

2011 chevy cruze code po2076


P2076 is Trouble code for the intake manifold tuning valve. You need to check power supply and signal to connectors. Check also the wirings. You can also monitor from the scan tool regarding the value of the position sensor of intake manifold tuning valve and the value commanded by the ecm. Sometimes this valve get stuck and will not respond to ecm controls. ?

What is a solution to fixing the mass air flow system, with code po121


DTC P0121: Throttle Position (TP) Sensor 1 Performance
Circuit/System Description
The engine control module (ECM) uses the following information to calculate an expected airflow rate:
?€¢
The throttle position (TP)


?€¢
The barometric pressure (BARO)


?€¢
The manifold absolute pressure (MAP)


?€¢
The intake air temperature (IAT)


?€¢
The engine RPM


P0121 The predicted air flow and the predicted MAP combined are outside a calibrated range for more than 3 seconds.
Circuit/System Testing

  1. Inspect for the following conditions:
  2. ?€¢
    Vacuum hoses for splits, kinks, and proper connections as shown on Vehicle Emission Control Information label


    ?€¢
    Inspect thoroughly for any type of leak or restriction


    ?€¢
    Air leaks at throttle body mounting area and intake manifold sealing surfaces


    ?€¢
    Throttle body for dirt, debris, and coking--Refer to Throttle Body Cleaning.

  3. Allow the engine to reach operating temperature. Observe the MAP Sensor Voltage parameter with a scan tool. Voltage should be more than 0.8 volt and less than 4 volts.
  4. ?‡'
    If more than 4 volts or less than 0.8 volt, refer to DTC P0106.

  5. Idle the engine. Observe the MAP Sensor kPa parameter with a scan tool. Increase the engine speed slowly and then back to idle. The MAP sensor kPa should change smoothly and gradually as engine speed is increased and returned to idle.
  6. ?‡'
    If the MAP sensor kPa does not change, refer to DTC P0106.

  7. Take a snapshot of the engine data list while performing the actions listed below. The mass air flow (MAF) sensor g/s should change smoothly and gradually as the engine speed is increased and is returned to idle.
  8. ?€¢
    Idle the engine.


    ?€¢
    Increase the engine speed slowly to 3,000 RPM, then back to idle.


    ?€¢
    Exit from the snapshot and review the data.


    ?€¢
    Observe the Mass Air Flow (MAF) Sensor parameter frame by frame with a scan tool. The MAF sensor g/s should change smoothly and gradually as the engine speed is increased and is returned to idle.


    ?‡'
    If the MAF sensor g/s does not change smoothly and gradually as the engine speed is increased and is returned to idle, refer to DTC P0101 or P1101.

  9. Inspect the throttle body for the following conditions:
?€¢
Loose or damaged throttle blade


?€¢
Broken throttle shaft


?€¢
Any throttle body damage


?‡'
If any of these conditions exist, replace the throttle body assembly.

2012 CRUZE DTC P2100


I had the same issue with my 2014 Cruze TDI. It was solid, every time I started the car the error would appear. So I disassembled the air intake and everything was clean except for the sensor between the MAF sensor and the throttle body. I have no idea why it was dirty when everything else was very clean. But I cleaned it a week ago and the light has not come on again. I hope this helps.

Po108 service code


Hi,
OBD II Fault Code
  • OBD II P0108
Fault Code Definition
The Manifold Absolute Pressure Sensor/Barometric Pressure Sensor measures the rise and fall of the air pressure inside the Intake Manifold. This provides critical data needed for the Power Train Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing, and many components of the Emissions Control Systems. The Manifold Absolute Pressure/Barometric Pressure Sensor converts the Intake Manifold air pressure into a voltage that is high when the Intake Manifold air pressure is high and low when the Intake Manifold air pressure drops to a vacuum. The P0108 code indicates a high voltage input from the Manifold Absolute Pressure Sensor/Barometric Pressure Sensor to the Power Train Control Module.
Symptoms
  • Check Engine Light will illuminate
  • In many cases, no abnormal symptoms may be noticed
  • In some cases, the engine may be hard starting and/or get poor fuel economy
  • In some cases, noticeably poor engine performance may occur
Common Problems That Trigger the P0108 Code
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is defective
  • Intake Manifold vacuum leaks
  • Faulty or corroded Manifold Absolute Pressure Sensor/Barometric Pressure wiring or connections
Common Misdiagnoses
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is an Intake Manifold vacuum leak
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is a stuck-open EGR Valve
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real problem is a defective Idle Air Control Motor, which causes a very low engine idle

2004 Grand Pix starting running rough all of the sudden. I tuned it up and replaced the engnition module and it still running rough any suggestions?


Electronic Engine Controls WARNING
To avoid personal injury and/or vehicle damage, refer to the service precautions at the beginning of this section.
General Information The Engine Management System (EMS) uses several different sensors and actuators to gather and control various emissions and driveability aspects of the vehicle. These may include but are not limited to:
  • MAP - Manifold Absolute Pressure Sensor
  • BARO - Barometric Pressure Sensor
  • FTP - Fuel Tank Pressure Sensor
  • ECT - Engine Coolant Temperature Sensor
  • A/F - Air Fuel Ratio Sensor
  • APP - Accelerator Pedal Position Sensor
  • CKP - Crankshaft Position Sensor
  • CMP - Camshaft Position Sensor
  • EGR Valve Position - Exhaust Gas Recirculation Valve Position Sensor
  • HO 2S - Heated Oxygen Sensor
  • IAC - Idle Air Control Valve
  • IAT - Intake Air Temperature Sensor
  • KS - Knock Sensor
  • MAF - Mass Air Flow Sensor
  • TP - Throttle Position Sensor

Are there any codes that point to a problem with any of the above sensors?

Codes p0113,p2104,p2111 pops up on 03 lincoln ls 3.9...any solutions


PO-113 Intake Air Temperature (IAT) Sensor 1 Circuit High Output

P-2104 Throttle Actuator Control Sysrem-Forced Idle

P-2111 Throttle Actuator Control System -Stuck Open

Without the vehicle,I won't tell you ,that you need to replace anything

The Throttle Actuator, is similar to Toyotas issuses with the gas peddle

To Diagnose what appears to be multipule issues,you need to check out the gas peddle sensors,the throttle body and the MAF Sensor,which has the AIT ,air intake sensor,part of it.

You could carefully remove the MAF and spray only with -CRC MAF Cleaner. Make sure the throttle plate moves relatively free. If you spray it,again Penzoil Throttle Body Spray or similar product

Most likely,your going to need a professional scan tool and some experience,to work out your problems.

You don't have wires,you have COP-Coil-On-Plug system.
If you have the codes,you could change the coils yourself.Their $59.00 at the auto parts store.

There is a misconception about tune-ups.
You only have spark plugs,and air filter,that would need replacing,that effect engine performance (Tune-Up)
Also, you can Clean the MAF Sensor,in the ducting,between the air filter and throttle body,with CRC MAF Cleaner. You could spray the inlet to the throttle
body,but I wouldn't bother.
I consider plugs& filters ,general preventative maintainance,nothing really tunes the engine,but it's own processors.

If you remove the coil cover, on top of the valve cover,you access the coils.Have to remove the coils to get to the plugs. The plugs aren't your issue,unless they have been in the engine for years or the valve cover O"Rings are leaking oil onto the plugs. Three coils seems questionable.

Get me the codes!

Why does reduce engine power light comes on chevy


That is a hard problem to pin point without knowing what codes the computer has stored. It can be any number or sensors or engine problems.

You can go to most auto parts stores and they will pull the codes for you for free.
