Engine code P1600 and P1449


The P1600 code is usually a IMA fault, and the P1449 code is a battery deviation fault.
Both are usually early warning of some sort of hybrid battery issues.
You need to have a system tech give the hybrid system a good look over, but most likely your IMA battery pack is most likely suspect

Engine code P1600 and P1449 what do they mean?

P1600 IMA system malfunction. A P1600 code is a generic code that is set in the engine computer to tell you that there is a Hybrid system problem. In order to find out what is wrong with the Hybrid system, you will need to take the vehicle to a Honda dealer so that they can read the code in that system.
P1449 Battery module,battery module deterioration, battery module overheating, battery cell overheating. Either way you need to take the car to a Honda dealership to find out the actual cause of the P1600 and replace teh battery module

Honda civic hybrid code p1433 and p1600

The P1600 is a generic OBD II code. It just means that a more specific code (Honda) has been set. To find the specific code you have to take it to the dealer or have a Vetronics Mastertech scan tool to get the actual code. The P1433 indicates thats the the main battery contactor or the by-pass contactor is staying active when it should not. Using an Actron pocket code reader will only read generic OBD II codes. Hope this helps.

I have a 2001 Toyota Ipsum 240e. The engine check light goes off when I disconnect the battery terminal. The light will not come on when the engine is run as long as required but once it is switched off...

You should have the error code read from the vehicle's computer (a code scanner is needed for this). If you constantly are disconnecting the battery, some manufacturers program an error code in the computer indicating that the battery has been disconnected within the last XX number of starts. If the code is P1600 or P1630, this is probably your problem. If you're disconnecting the battery for security reasons, either install an aftermarket security/anti-theft system or realize that the check engine light will keep coming on.
