Hello all, My Uncle is letting me drive his car for 1-2 weeks to look at a few issues. This is the same 2001 Eldorado ETC (currently 95470 miles) that I asked about the crankshaft position sensors last year. – thank you for the help then….
I got the car yesterday on easter but didn’t run codes until this morning. Many of these are battery related, so once I got them all written down, I have cleared the codes to see which ones come back. (none so far drove his car to client today for 9 to 10 miles). Only 1 current code, P0420 does concern me, I will look at the o2 sensor before and after to see output voltages, and look at catalytic converter for partial clogging…. I was planning on cleaning throttle body, changing any fluids that may need changing, looking at spark plugs, etc.
P0340 H – Camshaft Position Sensor Circuit
P0420 C – Catalyst System Efficiency Below Threshold (Bank 1)
P0560 H - System Voltage
P0562 H – Voltage Low
P0621 H - Generator Terminal Circuit
P1106 H – MAP Sensor Circuit Intermittent High Voltage
P1571 H – TCS PWM Circuit No Frequency
B1552 H – Keep Alive Memory (KAM) Error
B1161 H – Lamp Circuit Failure
B1327 H – Device Power #1 (Low Current #1) Circuit Low
B1552 H - Keep Alive Memory (KAM) Error
B1558 H – BCM EPROM Checksum Error
B1982 H – Device Power 1 Circuit High
B1983 H – Device Power 1 Circuit Low
B1327 H – Device Power #1 (Low Current #1) Circuit Low
U1004 H – Loss of Communication
B2119 H – Lumbar Forward Sensor Failed
B0856 H – Battery 2 out of range
B1983 H – Device Power 1 Circuit Low
My Uncle was having battery/alternator issues, replaced battery. Still had on and off issues with alternator not charging battery. Shop thought alternator bad. Week ago, battery taken out of car (car not at home, car dies on road while driving, needed towing couldn't jump as alternator not charging/running electrical). Battery taken home charged overnight, taken back to car and reinstalled. Car driven home. Few days later, seems that alternator is now charging battery…. I think my uncle accidentally fixed the short that was causing battery to not charge. Where is(are) a good place(s) to look for a loose connection that I can clean up and reset with good connection?
I will update after I get throttle body cleaned tonight, and if any codes reappear after I cleared them this morning.
