Why does my Honda Civic have a high idle speed?
Check the coolant level, it might be low causing the intake air bypass thermal valve to cool off and raise the idle speed. This happened on my civic. If the battery is low or has an internal draw it could cause this. Also if the altenator is having problems, it could lead to a high idle.
What’s the engine rpm on a Honda Element?
Pulled into a lot and put in park, and it idled from 1,000 to 2,000 and back and forth. While driving at a steady 50, it would feel like it was trying to find the right gear, a slight hic-up.
What’s the idle code on a Honda Element?
Note: this a 2008 E, it has a slightly different TB than the ones on the thread about cleaning the Idle control valve. There is only 1 connector, 2 coolant hoses, and one vacuum line on it, that’s it. Now, it has a new problem, it idles around 1200, and is giving a P0507 (high idle) code.
Why is my Honda Element engine surging in Park?
Check all of the vacuum lines, and the small rubber cap on the under side of the intake manifold (tough to see). You could also try replacing the idle air control sensor~$75. Check the coolant level, it might be low causing the intake air bypass thermal valve to cool off and raise the idle speed.
Why does my car idle at high idle?
If this tube becomes loose or broken it can leak un-metered air into the engine effectively causing an unbalance (via the mass air flow MAF sensor) in the computer system which can produce fast or slow idle.
Can a bad throttle position sensor cause idle surging?
Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges. 3) Check Engine Light
What causes idle surges on a car ECM?
Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges.
How can I check the idle air control?
To perform a rough check of the idle air control, remove the valve while reconnecting the wiring harness. While observing the valve with a flashlight, turn the key to the “ON” position, (DO NOT START ENGINE.) the valve should move slightly.
