The intake entrance is where the cable from the gas pedal meets the intake at a device that opens the first butterfly valve. The engine may require more cranks than normal to start, or may require multiple turns of the key. I feel one I located the imrc I can approached the solution better. So basically the inlet manifold runner control is a vacuum operated system that closes flaps inside the air intake to help with air flow at low revs and apparently increase mpg. Could it be a sensor or something else? It has actually had a really positive effect, engine is running smoother and idling at around 800 rpm but light is still on, so i think i will still order part and change it.
Under about 3000 rpm the vacuum solenoid will be energized. Commercial, heavy duty, custom, or off road vehicle use voids the warranty. Each set of butterfly valves are connected to the module by a link. If the unit malfunctions, it may not position the butterfly valves correctly, which can lead to. The motorized actuator houses internal switches to provide feedback to the Powertrain Control Module , indicating linkage and plate position.
If the intake manifold runner control has an issue it can cause the vehicle to experience engine performance issues such as , a , a , and even. I was thinking of doing it myself just with some carb cleaner, any thoughts? Not long just needed to stop and start a few times in traffic with engine warm and it soon happened. The light only shows when the ignition is on, but when I start the car the light now goes out! I tried something the other day Decarbonizing the engine with water. The intake manifold runner is on the lower intake manifold, under the upper intake manifold. Also will add all pics I have to help locate etc.
Theory is as the spray vaporizes, water expands, becomes steam and dislodges carbon deposits. If no faults are found, go to step 17. This will allow manifold vacuum to be applied and the butterfly valve plates to stay closed. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. The linkage attaches to the housing butterfly plate levers. To fit is a really easy process but fiddly to get to the hex screws due to wires. The Check Engine Light can also be set off by a wide variety of other issues, so having the computer.
Basically you get the engine up to temp then spay water directly over the throttle body. Thanks for all the help and info. After I replaced the idle valve I took the car for a drive and on every red light the car started to go off. If the computer detects an issue with the intake manifold runner control position, signal, or circuit, it will set off the Check Engine Light to alert the driver of the issue. Will keep updating if any problems later on.
So recently I have posted a few times about an intermittent fault I have been having where my car was losing power low down the revs and the eml kept coming on. The car was still getting the p2004 code. The Vacuum solenoid is getting signal but not opening, therefore it is the problem. Top tip mark on with a marker 1,2,3,4 and then also on the old air assy where they correspond when you get it off 3. Commercial, heavy duty, custom, or off road vehicle use voids the warranty.
If any faults are found, clean or repair as necessary. Ensure return springs operate properly and plates open and close fully. Once again, thanks for all the help really appreciate it. It has actually had a really positive effect, engine is running smoother and idling at around 800 rpm but light is still on, so i think i will still order part and change it. You say you had your throttle body cleaned, did you carry this out yourself? Thank you so very much for your help in advance. Engine misfires and decrease in power, acceleration, and fuel economy Another symptom of a potential issue with the intake manifold runner control is engine performance issues.
Original proof of purchase is required. This should hopefully then fix the issue. You have to remove intake to really see and work on it. This is on a metal plate with 4 vacuum hoses connecting to it. The plates then open and close to allow or restrict air from entering into the intake system. I did encounter some really viscous sludge around the throttle plate and just inside the throttle body, so i do think it needs cleaning.
Sorry for lengthy post and will post pics asap Sounds like the answer I have been looking for great work! Inlet manifold is at front of engine behind fan for radiator. If this happens, severe engine damage is possible, and could potentially cause engine failure. Hi Gregg, Thanks for link to thread really helpful :. I tried something the other day Decarbonizing the engine with water. The housing uses a return spring to hold the plates closed.
It is also important to note that similar symptoms can also be produced by other engine performance issues, so it is recommended to have the vehicle inspected by a professional technician, such as one from YourMechanic, to. The linkage attaches to the housing butterfly plate levers. I used a code reader and it showed up as P2008 intake manifold runner control circuit open. Above approximately 3000 rpm , the vacuum solenoid will be de-energized. What causes the P2004 code? This will allow vacuum to vent from the actuator and the butterfly valve plates to open. If any faults are found, go to next step.
