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 a Pontiac G6 v6 3.9 .. I have a code p2078 twice.. do I have to change the intake manifold tuning valve sensor or what?


What year is it ?
DTC P2078: Intake Manifold Tuning (IMT) Valve Position Sensor Circuit High Voltage
Associated with this code or any coded is a diagnostic flow chart ,for testing of the electrical circuit's for the position sensor . If you don't know that ,an know how to test electrical circuit's ,your best bet , take it to a qualified repair . Rather then guessing an just replacing parts .

Circuit/System Description
An intake manifold tuning (IMT) valve is used to change the intake manifold plenum configuration. When the IMT valve is open, the intake manifold is configured to one large plenum. When the IMT valve is closed, the intake manifold is configured to 2 smaller plenums. The IMT valve improves engine performance at low and high engine speeds depending on the engine load. The IMT valve assembly consists of the following:
• A tuning valve
• A microprocessor
• An electric motor
• A hall-effect sensor
• An ignition voltage circuit
• A ground circuit
• An IMT valve control circuit
• An IMT valve signal circuit

P2078
The engine control module detects an open in the IMT valve ground or a continuous short to voltage in either the IMT valve signal circuit or the sensor. This diagnostic runs continuous when the conditions for running are met.
Test the electrical circuit's !!!!!!! you would need a wiring diagram

Circuit/System Testing
Ignition OFF, disconnect the IMT valve harness connector at the IMT valve.
Test for less than 1 ohm of resistance between the IMT valve ground circuit terminal B and ground.
? If greater than the specified value, test the ground circuit for an open/high resistance.
Ignition ON, verify that a test lamp illuminates between the IMT valve ignition 1 voltage circuit terminal A and ground.
? If the test lamp does not illuminate, test the IMT valve ignition 1 voltage circuit for a short to ground or an open/high resistance. If the circuit tests normal and the fuse for the IMT valve ignition 1 voltage circuit is open, test or replace the IMT valve.
Connect a test lamp between the IMT valve control circuit terminal C and the IMT valve ignition 1 voltage circuit terminal A.
Command the IMT valve ON and OFF with a scan tool. The test lamp should turn ON and OFF when changing between the commanded states.
? If the test lamp is always ON, test the IMT valve control circuit for a short to ground. If the circuit tests normal, replace the engine control module.
? If the test lamp is always OFF, test the IMT valve control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the engine control module.
Ignition ON, test for 4-6 volts between the IMT valve signal circuit terminal D and ground.
? If less than the specified range, test the IMT valve signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the engine control module.
? If greater than the specified range, test the IMT valve signal circuit for a short to voltage. If the circuit tests normal, replace the engine control module.
Install a 3A fused jumper wire between the IMT valve signal circuit terminal D and ground. Verify the scan tool IMT valve Feedback parameter transitions from 0-100 percent.
? If parameter does not change, test the IMT valve signal circuit for short to ground or an open/high resistance. If the circuit tests normal, replace the engine control module.
If all circuits test normal, test or replace the IMT valve.

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
Long.

DTC P1078:
Intake Manifold Tuning (IMT) Syst
em Malfunction (High rpm) Stuck
Long
P1078-0570
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.

Code p2004 saying intake manifold runner control sturck open. bank 1


code p 2004 has two references
intake manifold air control actuator , bank 1 --actuator stuck open====causes ---wiring---intake manifold air control actuator ---mechanical fault
second reference is
intake manifold air control solenoid , bank 1 --solenoid stuck open===causes ---wiring--intake manifold air control solenoid ---mechanical fault

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.
