Who scanned it, the dealer? A pcm code doesn't necessarly mean it's is bad. You need a service manual and follow the flow chart. Without a top of the line professional scan tool and years of experience,I would just go to the dealer. If you replace it, you still have a lot of relean stratagies to put into it and only the dealer can flash your initial factory settings.

Check eng. light on. P0601 code What can I do?


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. 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 dealership for this). The good news is it *may* be covered under your emmissions warranty. good-day!

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.

P0601 internal controller malfunction


Isnt good; the bad news is, this is an internal failure. Sometimes you can clear the code and it won't return. But most of the time you need to replace the PCM. Something inside the logic get garbled and throws that code.

Good news...the PCM is an emissions related component. I believe it is covered under warranty for 8 years or 80,000 miles. Check with your dealer. Just like catalytic converters and such.

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.

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.

Hope this helps (remember to rating this answer and leave some testimonial comment).

Is it possible that the diagnostic result from the dealership would be wrong regarding the PCM defect. Their recommendation is to replace the PCM. It was diagnosed P-0601 Intenal failure code. My car is...


Take the van to AutoZone or similar business to get a free scan of the computer and see if you get the same error code. You should be able to replace the PCM with one from a wrecking yard--they guarantee them usually for at least 30 days. Dodge dealers and auto parts houses sell rebuilt ones too, but it has been a number of years since I had to buy one. Wrecking yards usually sell for half of new price. Hope this helps!

Check engine light is on 3 codes p0740,p0601,& p0700 what do they mean


P0700 - Transaxle Control System Fault Conditions
The P0700 code is for information only and the next step is to check for transaxle codes in the Transaxle Control Module (TCM). So you'll have to have the dealer or another qualified shop/technician pull the transaxle codes from the TCM and go from there.

P0740 - Torque Converter Clutch Circuit Malfunction

Basically that means that there is an interal fault in the Powertrain Control Module (PCM).

Ck eng. light comes on after geting gas code reades Po601


P 0601 = Internal Controller Failure. PCM (Powertrain Control Module) Internal fault condition has been detected.
To clear the Code (and Engine Light) from the PCM use a OBD II Scan tool. If you do not have one, go to an auto parts store. They can hook one up for free. Clear the code using the Scan Tool. It is not recommended to disconnect the battery to clear the PCM Codes, as it will cause the engine to run rough.
If the Code/Light re-appears, there may be a problem with something else.
Let me know if this helped, or if you have addtional information or questions. Feel free to contact me at FixYa.com!
