Dead Battery P0606 code
Hello, I’m am in need of some help. I have a 2005 Lincoln Navigstor with 140,000 miles. I am having some recent issues with the battery. From the looks of it it appears to be the original battery. Went out one morning to start my truck. It acted as if it didn’t want to start but it did. Drove it to work then went out that afternoon for lunch and it started without a hitch. When my shift was over came out to start my truck and again almost didn’t kick over but it did. Next morning didn’t start at all without a jump. Drove to work. Went out for lunch and again started right up withou any issues. This has been going for a few days. The truck sat for 2 days and the battery completely died. When I went to jump it this morning got it started but now I have check engine light with a P0606 code. Is this because of the dead battery or am I going to have to replace the ECM. Before all this happened I was getting a P0420 code which I know has to do with the catalytic converter. Can the issue with the converter be tied together with the ECM?

Mine was starting hard like yours about a month ago. After a few days, it wouldn't start without a jump. AutoZone said the battery was dead, needed to be charged/tested. I went home, pulled the battery and took back to them to quick charge. An hour later they said the battery was shot. It was 2 years old, Duracell from Sam's Club, got it replaced free, no questions asked. I put in the new battery and went back to AutoZone so they could check the alternator output and it was low. The alternator was about 5 years old, lifetime warranty from AutoZone, pulled and swapped now good to go for a couple more years. Florida heat and humidity is tough on charging systems. I'm petty sure the alternator went out and the few days of use with the bad alternator did the battery in. I never got a code like you did though.

Get the charging system and battery up to standard, reset the PCM, and retest. If the battery is failing, it can cause the reset of the system to do som strange stuff.

A 12+ year old battery? Sounds like a no-brainer to me, replace it.
