Ok, we here found a problem similar to this, the 2006 RX8 we had has a problem with the sensor at the end of the IMT valve, which lets the computer know weather the valve is open or closed. Have a technician OHM the sensor, IF it reads open and closed, remove the valve, and clean , then clear code and drive.

SOURCE: Need to tow 04 mazda rx 8

Top left and right corners of the front grill pull away to reveal the fixing holes. Make sure you WD40 the threads as Mazda coat the threads with paint. insert towing eyes and turn slowly unscrew and screw a bit at a time as you have a good chance of cross threading if you don't. Keep lubricating as you go. Make sure you take the plastic inserts off completely before towing as you will loose them when towing. replace when completed towing. Good luck and hope what ever the reason for towing it is not serious.

SOURCE: mazda rx8 fault code p0410

The P0410 code refers to the (secondary air system) emissions system. The AIR pump puts air to the exhaust to lower emissions. It takes in outside air and pumps it through two one-way check valves into each bank of the exhaust.
.
About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water (which occurs naturally in the exhaust) back into the pump. In any cold climate, especially in climates with higher humidity, this water may be more excessive. The water partially fills the AIR pump, it can then freeze. When the PCM commands the pump on, if the pump is frozen it cannot turn, thus overloading the circuit and "popping" the fuse.

A code P0410 may mean that one or more of the following has happened:

  • Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump
  • Blown AIR pump fuse due to freezing up
Possible solution:
This may be covered under the emissions warranty on the vehicle. If your vehicle is out of bumper-to-bumper warranty, check if the emissions warranty is still valid!
  • Replace the AIR pump AND one-way check valve
  • Test and clean the AIR pump AND test and replace the one-way air check valve
  • Replace the AIR pump inlet hose
  • Replace the AIR pump fuse (found under the hood)
It is really only an emissions issue and won't harm your car's engine ot drivetrain. It will however mean you won't pass emission testing if you live somewhere that tests for that like I do!

I have a 08 uplander i just put a throttle body on and now i have a code p2070 intake manifold tuning valve stuck open how to i fix it


sounds like you have to do a cable adjustment.
if you have two people one of the easiest ways to do this is have someone inside the drivers sine press the gas pedal all the way to the floor.
Loosen up all the hold down cable connectors near the throttle body.
Re position cable tauntness so the valve body is open full and not a pinch more.
Tighten everything in place then release gas pedal.
you should have enough play in the cable for the sensors to register zero.
now clear the code should be no more problem, works on just about any car that has fuel injection.
appriciate a rating, Gary

P0660


Po660 means "Intake Manifold Tuning Valve Control Circuit/Open".it't means as same as "Engine Light ON (or Service Engine Soon Warning Light".The Intake Manifold Tuning Valve (IMTV) system is monitored for failure during continuous, key ON engine OFF or key ON engine running self-test. The test fails when the signal on the monitor pin is more or less than an the expected calibrated range

 

what is the reason?
1,IMTV signal circuit open, shorted to power or ground.
2, Damaged IMTV actuator.
3,Damaged PCM.
