P0601 means your engine computer has an internal error; P0606 means that the engine computer has stored in memory exactly the running condition( much like a "black box") that the vehicle was in when the P0606 was triggered. P1518 also relates to the PCM in the matter of low voltage.

Try testing the battery as improper voltage can cause all of these codes. Otherwise it means that your PCM has failed and either needs to be reprogrammed or replaced.

This pretty much means that your computer has failed. The engine will go into limp mode at this point, as you have noticed. You need to have the computer tested, but really the only way to do this is at a dealership. Most mechanics won't have the right tools. A dealership might be able to reset your computer and get you going again. You should be prepared, tough, to hear that your computer is shot and can not be fixed. In that case, you're looking at $600-$800 for the part it's self.

However, you can try to monkey around yourself. Disconnect the wiring harness from the PCM and make sure both connectors are clean. Reconnect the wiring harness. Go around the engine and make sure all ground connections are clean and tight. A bad ground in the wrong spot and really mess with the computer too. I wish I could be more specific, but it's really a matter of just hunting around the engine and making sure everything is tight and clean.

SOURCE: what is a code 1258 on a 2005 chevy equinox

DTC P1258: Engine Coolant Over-Temperature Protection

The powertrain control module (PCM) has the ability to disable 4 injectors during an engine over-temperature (overheating) conditoin. Engine is considered over-temperature whenever the engine coolant temperature reaches 268 F. This protection mode allows the PCM to alternate between groups of cylinders, thereby reducing coolant temperature. This is accomplished by disabling the fuel injectors. This DTC is set to show that an overheating condition was or is observed by the PCM and that the protection mode has been engaged.



You will need to inspect the cooling system to see what is causing your overheating issue. If the engine is not actually overheating, this code may be set due to a faulty engine coolant temperature (ECT) sensor.



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.

I have 2006 chevy equinox code po455 I change the fuel cap and the purge evap valve but my code comes back what else could it be?


As you know one of the problems can be the Fuel Cap. I make this suggestion. If you changed your Fuel Cap before the Purge Valve double check that the cap used was an OEM (Original) Chevy Part for that specific vehicle, not just any cap from another Chevy.

Error code p062b 2012 equinox


Had the same problem on our 2012 Equinox today. Threw codes P026B and P062F. Appears to be a bad battery. Replaced battery and all seems ok now...keeping fingers crossed. My suspicion is that the faulty, dying battery caused a low voltage situation in the injector control module and thus those errors. Will see if the check engine light returns in the next 48 hours.

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.
