Question about 2000 Honda Odyssey

1 Answer

RPM's rev high and low

I have owned my odyssey for 4 yrs now with no problems. Now I know I have an O2 sensor out but sometimes it will idle really low almost stalling out and then run fine for days or weeks. Then out of no where it will rev up to 1800 then down to 1100 rpm's. Tried shutting off then turning back on with no resolve. Could this be a throttle positioning sensor problem? The whole van is slowly falling apart lol. passenger sliding door does not operate as well think this is due to the rollers falling off sending a fault to it shutting the door down.

"Could this be a throttle positioning sensor problem?" - probably not. The Throttle Position Sensor (TPS) tells the computer how hard you are stepping on the gas. It does not really control idle speed.

Your problem is more likely the Idle Air Control (IAC) valve. This is a small electric valve that the computer can open and close in small steps to set the idle RPM at the desired point (a little higher when cold, then down to normal speed when warm). The IAC valve is notorious for getting all crudded up inside. Then it sticks open too much (really fast idle speed) or sticks shut (really low speed).

You can try taking it off the engine, cleaning it with carb cleaner spray, and putting it back on. That is easy and cheap.

If cleaning does not fix it, you need to buy a replacement valve and put it on. Pretty easy to do but costs more $$$.

SOURCE: 2004 Honda Civic -Code P0122 Throttle Position Sensor Voltage Low

yes, this is the case of a failed throttle body, in which case it needs replaced, the car is getting too much fuel causing the high idle. this needs replaced asap. you could proably find a small independant honda shop that could do the work for less.

SOURCE: under 2000 rpms runs bad/hesitates/check engine light

This IAC valve runs only when your foot is off the gas pedal. Mainly to keep the engine from stalling and keeping it at a safe RPM. If it is running bad under 2000RPM, more than likely its the IAC valve or a vacuum leak. Clean or replace the IAC valve....Hopefully this helps!!

It sounds like it could be a distributor problem too. Cause that also controls the idle and timing of the engine.

Idle problem integra


check the MAP sensor (manifold absolute pressure). The ECM (car computer) uses that to keep idle at minimum 750 RPM. It's normal for it to run high when cold. These small 4 banger motors typically run hot, and they won't run right IF they're NOT running hot, ergo the idle is usually high when it is cold so as to cause it to warm up quicker. If the RPM's drop below 750, suspect the MAP sensor, &/or ECM.

Surging and dropping idle


It could be an o2 sensor. When you are unplugging your battery it causes it to rereset and loose its memory. If the o2 sensor is going out it can cause false readings leading the problems you stated. You can take it and get it scanned you can do what I did and go ahead and replace all my o2 sensors. I figured since one when out, the rest wouldn't be far behind.

The most common cause of high idle is an intake air leak. It will cause a lean condition to the O2 sensors and the PCM's solution is to increase the fuel mix resulting in faster idle. It can also cause a Check Engine Light if the idle remains too high for too long. Do a smoke test or soapy water test around the intake manifold and throttle body. If you detect any leaks, seal them and try again.

Sounds like a broken or torn vacum hose, pcv valve clogged, or bad Idle air control motor. Did you spray carb cleaner on vacum hoses or near the plastic intake., and did the motor rev up or down? Those codes represent a lean condition which means most like a vacum leak or clogged idle air motor. Sometimes the intake manifolds crack or the intake manifold gaskets crack. FInd that vacum leak or inpect iac motor

I'd lean toward the MAP/MAF sensor because of the rev limit. A car with a bad O2 sensor will still rev to redline - it'll just be running rich the whole time. Some manufacturers put in a rev limiter that kicks in if the MAP/MAF sensor goes bad, so I'd lean that way first. Clean the electrical connector with contact cleaner, and run a half a can of Seafoam through the vacuum system - this may clear up your issues. If not, I'd replace the MAP/MAF sensor before the O2 sensor.
