I am having a multiple cylinder misfire on my 2006 Toyota RAV4 with the 3.5L V6. Every cylinder is reporting a mifire. Each cylinder has it's own coil. I highly doubt that all 6 coils went bad at once. Does anyone have any idea what my be causing this?? Is that the problem you two are having?

P0606 code on 2003 Saturn Vue AWD 2.2l check engine light on


Hi there:
P0606 is a internal computer fault. Sometimes extreme hot or cold weather will screw up a computer.




P0606 - PCM / ECM Processor Fault
This code is a fairly simple one. It basically means that the PCM/ECM (powertrain/engine control module) has detected an internal integrity fault in the PCM. When this code is activated it should store freeze-frame data that helps someone with an advanced code scanning tool to get information on exactly what was going on with the vehicle when the P0606 code was triggered.



Most likely the only symptom of a P0606 DTC code is the illumination of the "Check Engine Light" a.k.a. MIL (Malfunction Indicator Lamp).



Cause: In all likelyhood the PCM / ECM has failed.


Possible Solutions: As a vehicle owner there is little you can do to fix this code. The most common fix for a P0606 code is to replace the PCM, although in some cases re-flashing the PCM with updated software could possibly fix this. Be sure to check for TSB's on your vehicle (Technical Service Bulletins).


In all likelyhood the fix is to replace the PCM. This is generally not a "do-it-yourself" task, although in some cases it may be. We strongly recommend you have a qualified repair shop / technician do the work, one that has the capability to reprogram the new PCM. Installing the new PCM may involve using special tools to program the vehicle's VIN (vehicle identification number) and/or anti-theft information (PATS, etc.).


NOTE: This repair may be covered under the emissions warranty so be sure to check with your dealer as this may be covered beyond the bumper-to-bumper or powertrain warranty period.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

The vsc, 4wd, airbag light and check light just came on whilst driving. it's a 2006 limited edition V6, RAV4, but now the airbag light has gone off, the other lights are still showing. What do you think...


It is a possibility that that you need a speed sensor, or a battery somebody with a good scanner has to check for engine,abs,airbag codes. If the mechanic that is scanning your vehicle is not familiar with toyota found multiple codes en different systems the problem is the battery.
If the problem-is a speed sensor code, then there is service bulletins that advice you to replace hubs and wires, that is really spensive but necessary. Water intrusion is the problem, creates corrosion that spays in the sensor and wire, if you replace only one the other transfer corrosion to the new item. Good look Nikky.

P0601 diagnostic code what is the mean , or whats is the problem


P0601 - Internal Control Module Memory Check Sum Error

Basically that means that there is an interal fault in the Powertrain Control Module (PCM). There have been many reported PCM failures on Chrysler/Dodge products although it is possible for this to happen on any vehicle. In Dodge/Chrysler products, a P0601 trouble code means that a serial communication failed inside the computer at least 6 times.

Symptoms: Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light. Typically the engine runs fine, gauges work, etc.

Causes: A code P0601 in most cases means the PCM has gone bad. This is possibly due to a short-circuit inside the PCM. Or, if you disconnect the wires/connector from the PCM while the battery is still connected, that may also cause this code.

Possible Solutions: With a P0601 OBD-II trouble code, the most common fix is to replace and reprogram the PCM. In a few cases the dealer may be able to reflash the PCM and get it working. But more than likely the PCM will need to be replaced and reprogrammed (we recommend you take it to a dealership for this). The good news is it *may* be covered under your emmissions warranty. So even if you're out of bumper-to-bumper warranty or powertrain warranty, check your warranty guide or dealer to see if this is covered.

Other people have reported that they cleared the code only for it to return again and again. Keep in mind that most shops can replace the PCM but not all can program it.

Other PCM / ECM Codes: P0602, P0603, P0604, P0605, P0606, P0607, P0608, P0609, P0610.

Hope this help to solve it (remember rated this).

2006 RAV4 V6 multiple cylinder misfire, VSC, check engine and sli


You need a scanner to pull out the engine light codes.
Use a shopu manual to aid you with the diagnosis and repair.
The slip indicator and vsc light being on means these systems are not working. Once you pull the codes and do the repair and erase the codes the lights will go off.
There will be a code in there for the misfiring.
Good luck and keep me posted.

When i started my 2006 rav 4 this morning these lights came on and are still on, brake light,4wd light, ABS, VSC LIGHT?


If you had your foot on the brake while starting brake light could come on. If a catalytic convertor does not pass at startup (possibly ox sensor or whole convertor) then the computor turns 4wd vsc and check engine light on. note the six cylinder has three catalytic convertors and the four cylinder has two. Very expensive if convertor(s)
