![]() The 12v is charged by the high voltage battery.This is my first hybrid vehicle, so maybe I am misunderstanding something, but alldata and rockauto both seem to indicate that my vehicle does indeed have an alternator (although alldata often using the term generator and alternator interchangeably). You won't find a alternator on this vehicle. ![]() (2) Anyone know what needs to happen in order for the P0562 code to clear (it is being thrown by the TCM, not the PCM)? Is there a good way for me to confirm my alternator is working properly? I'd hate to damage my brand new battery. With the car running, the battery voltage is 13.5V-13.9V which seems a bit low, but I can't find a specification for what the voltage should be and my assumption is that hybrid cars might have different charge voltages than more traditional vehicles. ![]() (1) How can I make sure the alternator is good? In the past I have had bad alternators that cause my batteries to fail prematurely. I am not sure what needs to happen for P0562 to clear, but clearing the code from my OBD2 scanner isn't working, I am hoping there is another OBD2 self test that the vehicle needs to run in due time that will clear the code now that I have replaced the battery. I am 95% P2450 will go away once the "Evaporative System Readiness Check" completes. The DTC codes P2450 (Switching Valve Performance or Stuck Open) and P0562 (System Voltage Low) remain. I have since put in a new battery, cleared the codes, and driven the vehicle about 40 miles getting 7 of the 8 ODB2 tests to run. My first inclination, knowing that the 12V battery had tested weak, was that the battery voltage got too low and caused a bunch of sensors to incorrectly report problems. So, I buy the car, get 20 miles down the road and the check engine light comes on. There were zero DTC codes, no check engine lights. The 12V battery was almost 5 years old and was due to be replaced. Relevant to this thread, the inspector had load tested the 12V battery and determined it was weak (in case you were wondering the hybrid battery tested fine). He found a few issues, but nothing bad enough to scare me off the vehicle. As far as I can tell, the inspector did a good job. I tend to get emotional and anxious when purchasing cars and it is near impossible for me to keep my wits about me in order to do my own thorough inspection. I paid a "lemon busters" company $170 to inspect the vehicle before purchasing. But now that gas costs $2.50 per gallon, neither my dog nor I miss having such a beast of burden occupying the driveway.I just bought a 2010 Escape Hybrid with 100k miles. When my thoughts drift in the truck direction - a rare occurrence I must add - what appears in my mind's eye is a well used, low-built, park-out-doors pickup. It's comparable in base price to the Escape Hybrid but delivers a few more miles per gallon. And for those who've gotta have a hybrid, my recommendation is the highly competent gas-electric Fusion. So instead of shelling out more than $30,000 to drive a 30+mpg Escape Hybrid, I'd lean strongly in favor of a low-end Fusion that costs about ten grand less, comes close in mileage, and easily matches the Escape's 1000-pound tow capability. That doesn't jive with my personal experience because the pets that allow me to share their home prefer the easier climb aboard and more cozy seating provided by just about any coupe or sedan. One of the most frequently cited justifications for purchasing a small crossover is to transport the family's canine(s).
