How can I fix Check engine light and IMA light that is on a honda Civic HYbrid

Asked by Feb 23, 2015 at 11:21 AM about the 2003 Honda Civic Hybrid

Question type: Maintenance & Repair

Honda CiviC 2015-02-17 11:00 I have a Honda Civic 2003 Hybrid with 169,000 miles.
My check engine light is on and the IMA light came on. The code for check engine is
P1600 which is a genersal code.When the rechargeable battery went down to no bars
and recharged , the check engine light and IMA light went off. For a few weeks they
stay off. It came back on. Usually, When I fill the tank with gas it does city 39 miles
gallon . Few days later it drops to 20 miles per gallon. One mechanic told me I need a
special terminal battery for Hybrid cars. He said my rechargeable battery is at 70
percent. I told him I changed the Terminal battery three times because the voltage
was not being held . Another mechanic told me I need the rechargeable battery
replaced because three cells are not good and my terminal battery is being over used
because the IMA battery is not good. Does any one know why I am not consistently
getting 39 miles a per gallon? Should I buy a special battery for Hybrid cars, get the
rechargeable battery replaced or can I get recharged the bad cells if that is the
problem, or try to find another reason for my car issues?
