I was driving to the dealership this morning to have a wrongly installed serpentine belt installed correctly, when my "Check Engine" light came on. The truck had has an electical issue and had seen three alternators and two batteries installed in the past 4 weeks, and the mechanic routed the belt incorrectly when he installed the alternators. I took the truck to Autozone today and received these codes:

P0130 - O2 Sensor
P0560 - System Voltage

What would you suppose the problem would be? Remember, the light came on PRIOR to the dealer fixing (properly routing) the serpentine belt. Also, the truck seems to be driving perfectly.

 

The voltage one dont worry about, you had a pending fault with the battery going dead so often in such a short amount of time.
Clear that code and it wont come back.
As for the O2 code, when was the last time the truck had a Tune up?

 

Get back to us and let us know what they say.
Have you already replaced your 02's, how many miles on the truck?

 

How do you clear a code (per Spike555's post)?

The truck has about 160K miles on it. I do not recall when it was last tuned up, nor if/when the O2 sensor has been replaced.

 

Well 98% of all O2 codes on LR's are because of bad plugs and wires.
Here is what I would do, go and have the check engine light turned off (codes cleared) and see if the light comes back on.
With your voltage being so low so often for so long if your O2's also had low voltage it could set off a O2 code.
So you will either need to buy your own OBDII scanner for around $30 or have a shop clear the codes.
AuroZone used to do it for you but not anymore.
There is no other way to clear the codes than a OBDII scanner.
On the plus side once you own a scanner you can read your codes anytime you want without a trip to the shop.
If the O2 code comes back then we can talk about a tune up.

 

You can buy a OBDII scanner almost anywhere.
AutoZone, Wal_Mart, Target, etc.

 

OK. Thanks. I'll get that taken care of.
