SOURCE: malfunction indicator light is stuck on.

If the light was flashing when it came on, then it means your engine is misfiring.
A solid light can mean anything. loose gas cap (which you ruled out) to a problem with the transmission

This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain off. If the light turns off, then it has detected that the issue may no longer be present.

In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. Most garages will do this free of charge. The code will tell you what may have caused the light to initially go on

SOURCE: i have malfunction indicator lamp on how i can fix that

I have the same problem and took to ULTRA TUNE and after general service they said cant figure out the issue and asked me (on car pick up) how many times i had that light ON (answer is three times ON and OFF just in morning and after engine warm up then its goes OFF after restart) . Then day one from service i have the same problem and took it again to ULTRA TUNE (good news is i dont have to pay again to look into issues within 6 months of service) and after scanning the board they said cant figure out the issues and probably it might be either spark plug issues or sometime unleaded petrol may cause this and advised to change the fuel to premium petrol for week and then check. As expected no luck with premium petrol and third time they cleaned the throttle (full clean up) and advised the spark plug is okay and no need to change and as well as everything looks okay and advised to give a try. I went straight to GYM and back to car and started engine and got the lights TURNED on :( Its really furstating me now . CAN ANYONE PLEASE ADVISE how to handle this now?? IS HONDA service center is only place they can tell whats the issue is???????

SOURCE: is there an erg valve on a honda accord 2008 4 cyl

code p0300 refers to--random/multiple cylinder/s misfire detected...Causes---spark plugs---HT leads---injectors---ignition coils ---low compression ---wiring
code p0302 refers to cylinder 2 misfire detected Causes ---engine mechanical fault---wiring---ignition/fuel system ---ECT/MAF sensors ECM
code po303 refers to cylinder 3 misfire detected Causes Engine mechanical fault---wiring---ignition/ fuel system ---injector---ECT/MAF sensor ECM The common fault to all is the fuel/system ignition
I would have the injectors checked and have a pressure test done on the fuel manifold to check pump and fuel regulator valve.

I have engine codes;p2070,p0128,p0605,and p0457 and i dont know what they are let alone how to fix said issues

nobody does.... that is why they have ASE school.
here is a list of starting places.
1: check all fuses.
2: then post all driving and running symptoms... (got any?)
3: then scan it ( you did)
4: then look each up in the FSM (p2 code is Suzuki only code so...)
5: then do the tests the book says to do , to find real cause
the PCM never knows what is wrong, it only knows tests fail , only.

here, ill look at and look (so can you) USA cars.... so........
2070 is IMT stuck.
IMT is varible intake induction ports. (small /large )
this new feature allows better low end engine torque. (fancy )
Trouble Code Conditions:
Ignition ON. No IMT valve position sensor fault exists. No IMT valve solenoid fault exists. Ambient temperature is greater than -9.75 C (14.45 F). Battery voltage is between 9.95 and 25.89 V. DTC P2071 is not set. IMT valve flap is not completely closed.
Possible Causes:
  • Vaccum leakage from hoses or connections.
  • Vaccum reservoir.
  • IMT valve solenoid.
  • IMT valve position sensor.
  • Excessive mechanical friction in the flap operation.
Coolant Temperature Below Thermostat Regulating Temperature is your thermostat , 8 years old, ??????????
what a tech does is read the temp and if too l low does tests to find cause., we never guess. do simple tests. ask how.

605 (a horror) i've no idea. (reset and pray) Trouble Code Conditions:
A) ECM calculation function is malfunctioning. B) ECM EEP-ROM system is malfunctioning. C) ECM self shut-off function is malfunctioning. NOTE: The ECM enters fail-safe mode when malfunction A is detected: * The ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx. 5 degrees) by the return spring. * The ECM deactivates ASCD operation.
Possible Causes:
  • * Faulty ECM

Evaporative (EVAP) Emission System Fuel Cap Leak Detected gas cap loose?
this means, the tank vent , is breached, or the controls bad.
we tighten the cap , reset the codes and drive, if comes back.
test cap or get new one. or if cap is good. we do the leak down
test fully stated in the FSM. (by the book) read it. its very clear.

what id do is fix the 2070 first.
then reset all codes drive and see what comes back.

what i do, is look at out door temps. is it -20F out or +70F?
i dont know your location so cant guess.
but if not fridge out, i make sure the engine hits 180F coolant temps
at a normal runnning time. (normal) if its too low or too slow the stat is no good. if the fan is stuck on, FIX that first. because a stuck on fan
in fridged temps,can in fact slow a engine warmup time.
I use a tool ($20) that is an IR Pyro temp gun.
I point it at the thermostat housing, and look at the temp hot.
then scan the PCM and see what the ECT shows.
if they agree, the PCM was not fibbing. see?
lets say it reads, 150 hot. bad, and the ECU shows 151
they do agree. and the water is too cold.
we then do test to find out why,
if the fan is off, then a new thermostat is the next act.
way up north we have cardboard blocking the RAD to get
faster warm ups and full cab heat. so....... location is everytinng
Alaska or Key west, FL?, things are different there.

I always work cooling first, because the PCM just HATES
frigid motors. causes all else to go , lil crazy.

Pressure Control Solenoid C - Coe P1078

06 CR-V
when you hit the dear, things can break. what's surprising there?
id get a car safety inspection, road worthy ness checks.....really.
google is not your friend here, not for P1 codes. (unless very careful)
and the P1078 code only works on Hondas.
Not only that autozonded scans may show the wrong code.
why? because their scan tool is junk, ! (SSDD)
the FSM covers that 100% read that. for all the tests.

ill pretend the scan tool is not junk and reads Honda's correctly.]

P1 codes are factory codes, and reading ford, or chev or ? on that will
all be lies. P1078 is:
DTC P1078:
Intake Manifold Tuning (IMT) System Malfunction (High rpm) Stuck

DTC P1078:
Intake Manifold Tuning (IMT) Syst
em Malfunction (High rpm) Stuck
General Description
The intake manifold tuning (IMT) valve position sensor is mounted on the diaphragm valve shaft to detect a malfunction in the IMT valve.
The engine control module (ECM) / powertrain control module (PCM)
checks both the IMT solenoid valve command and the IMT valve position sensor output.
If the IMT valve position sensor output is Short (short runners) while the IMT solenoid valve is OFF, a malfunction (IMT remains Short / closed ) is detected and a DTC is stored

(what does this mean)
bar stool answer.
the deer hit my car.
the vacuum line fell of the IMT VSV and now the slave sensor fails.
there are 3 parts to the VSV (PCM command) sends vacuum
to the slave , then slave rod moves, the sensor in the slave
(readback pot) shows that it did move correctly
yours is stuck long.

Ford F140 4.2 Do Engine codes P0305, P0306, and P1518 relate to each other

I am assuming you mean F150 truck.
The answer is maybe.
Code 305 and 306 are missfire codes for cylinders 5 and 6.
Code 1518 is for a problem with the intake manifold runner control which could cause the other two codes.

P1518 FORD Description The Intake Manifold Runner Control (IMRC) is monitored for failure during continuous or key ON engine OFF self-test.
Possible causes - Intake Manifold Runner Control (IMRC) harness is open or shorted
- Intake Manifold Runner Control (IMRC) circuit poor electrical connection
- Faulty Intake Manifold Runner Control (IMRC) actuator
- Faulty Engine Control Module (ECM)

Mil comes on with p2004/ check valve stuck open. Where is the check valve located

P2004 - Intake manifold runner control (IMRC) stuck open (bank 1)
Description - This DTC is set when the IMRC is commanded closed, but the IMRC monitor indicated open. This DTC replaces P1518 and P1537.

Probable causes - IMRC monitor signal circuit shorted to PWR GND or SIG RTN
- Damaged IMRC actuator or solenoid
- Blocked vacuum hoses

Diagnostic aids - Monitor the IMRC and IMRCM PIDs. The IMRCM state should change when the IMRC is commanded open or closed.

This control valve generally is located on the back of the intake.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

2005 F150 5.4 Cuts off when driving at constant speed and show "Engine Fail Safe Mode" on display. It will crank back up and run for several hundred miles before doing it again. P2112 Throttle Air...

unfortunately no ! Your best bet take it to the dealer . The P0420 always ends up being the catalytic converter ! P2104 isn't throttle air control . P2112 - Throttle Actuator Control (TAC) System - Stuck Closed. Description: This powertrain control module (PCM) fault status indicates the throttle plate is at a lower angle than commanded. Possible Causes:
  • Binding throttle body, stuck closed.
  • Damaged PCM.
Diagnostic Aids: Application Key On Engine Off Key On Engine Running Continuous Memory All GO to DV1
P2104 - Throttle Actuator Control (TAC) System - Forced Idle Description: The TAC system is in the failure mode effects management (FMEM) mode of forced idle. Possible Causes:
  • Open or short in multiple accelerator pedal position (APP) sensor circuits.
  • Damaged APP sensor.
  • Damaged powertrain control module (PCM).
Diagnostic Aids: This DTC is an informational DTC and can be set in combination with a number of other DTCs which are causing the FMEM. Diagnose other DTCs first. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to QE1
P0506 - Idle Air Control (IAC) System RPM Lower Than Expected For Vehicles With Electronic Throttle Control (ETC) Description: This DTC is set when the powertrain control module (PCM) detects an engine idle speed that is less than the desired RPM. Possible Causes:
  • Air intake restriction.
  • Exhaust restriction.
  • Engine mechanical fault.
  • Damaged electronic throttle body (ETB).
  • Damaged PCM.
Diagnostic Aids: This DTC is informational only and it may be accompanied by other DTCs. Diagnose other DTCs first. If other DTCs are not present inspect the intake air system for air restrictions and damage. If no concerns are present, clear the DTC and retest. For All Others Description: This DTC is set when the powertrain control module (PCM) detects an engine idle speed that is less than the desired RPM. Possible Causes:
  • IAC circuit open.
  • Air inlet is plugged.
  • B+ or VPWR to IAC solenoid open.
  • Damaged or incorrect IAC valve.
  • IAC valve stuck closed.
  • VPWR to IAC solenoid open.
  • IAC circuit shorted to PWR.
Diagnostic Aids: Disconnect the IAC valve and look for little or no change in engine RPM as an indication of a stuck or damaged valve. Application Key On Engine Off Key On Engine Running Continuous Memory Vehicles With Electronic Throttle Control (ETC) Refer to the Description, Possible Causes and Diagnostic Aids for the DTC. All others GO to KE1
