Hi,

I have not come accross a P2225 error code on a Toyota (Sienna). Best I can gather is this error indicates "NOx Sensor Heater Sense Circuit Intermittent (Bank 2)". on an OBDII Code Reader.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Why won't my 2002 Toyota Sienna idle on it's own? I have replaced the Throttle Positioning Sensor already.


Clean the IAC motor and inside the throttle body. This will fix your problem.

Clio auto gear selector the A keeps turning off


possible causes
- low transmission fluid level
- dirty transmission fluid
- faulty line pressure solenoid valve
- line pressure solenoid valve harness is open or shorted
- line pressure solenoid valve circuit poor electrical connection

when the a transmission solenoid is stuck off, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. if the transmission fluid is very dirty, it is recommend changing the transmission fluid and if possible removing the transmission pan for further diagnosis. excessive debris or metal particles on the transmission pan could be an indication that there is a transmission mechanical failure and that the transmission will need to be rebuilt or replaced.

The code P0601 means the internal memory of the PCM (computer) has failed self-test. The PCM may need to be reflashed or replaced. The other codes will probably go away after this.

OBD code P0746. Where is the Pressure Control


P0746 Pressure Control Solenoid Performance or Stuck Off
A transmission solenoid is an electro-hydraulic valve that controls fluid flow into and throughout an automatic transmission. Solenoids can be normally open or normally closed. They operate via a voltage or current supplied via the transmission computer or controller. Transmission solenoids are usually installed in a Transmission Valve body, Transmission Control Unit, Transmission Control Module or inside the Transmission and it helps regulate the pressure from the trans fluid pump.


P0446 Evaporative Emmission Control System Vent Control Circuit Malfunction

What does that mean?
Evap vent valve has only one purpose. It closes in order to seal the vent so the EVAP system can pressurize and ensure there are no leaks. Evap vent valve is usually supplied Batt. voltage with key on. The ECM's driver controls the ground, and when grounded, activates the valve (closing it). If the ECM detects a short to ground, and open,or a short to battery voltage on the control circuit, P0446 will set. Code also may refer to ECM detecting that EVAP system is unable to achieve or maintain vacuum during test.

Symptoms
There will be no obvious symptoms to driver, other than MIL illumination.

Causes
A code P0446 could mean one or more of the following has happened:
* Faulty vent valve
* Open, short or excessive resistance on Vent valve control circuit
* Blockage of vent valve
* Bad PCM

Possible Solutions
With a P0446 OBD-II trouble code, here are some things to try:
* Replace Vent valve
* Repair open, short, or resistance problem in control circuit
* Repair open, or short, or resistance problem in power circuit
* Replace PCM


Hope this help (remember rated this post).

2003 toyota sienna idle problem


After about 100K + miles the idle air control valve (IAC) begins to collect carbon deposits that interfere with the movement of the spring-loaded valve. You will not be able to clean this without removal and dissembly of the IAC body. Use an emory cloth or fine sandpaper to remove the build up around the valve. This should free it up to rotate without binding. This is a temporary fix, of course, and will either require cleaning again or replacement of the valve. Getting to the IAC requires removal of most of the intake upto, but not including, the intake manifold. Total time is approximately 3-4 hours, but worth it. Good luck, and I hope this helps.
