1998 Plymouth Voyager 6 cyl Automatic 100000 miles
i hav a p1478 fault code. Which is battery temp. Out of limit.I cant seem to locate the battery temp. Sensor. Is it internal of the pcm.I checked the charging volts at the battery with a charging system tester and it bounces between normal charing range to over charging. Can a bad alternator cause this fault?The alternator does hav a little whining noise coming fromit also. My coolant temp gauge on the dash doesnt work either unless im driving for an hour or so. And I let it idle in park or drive(but not moving) the temp will jump to normal operating range. Dont know if its stuck open thermostat or bad coolant temp sensor.I do seem to get heat 10 mins after initail start from cold eng? Any input apprec.
have the same problem?
