I've been getting an intermintent check engine light. It will come on, and then within two or three strarts go away. Sometimes it's days or weeks before I see another one. Took it to the shop and here is what was discovered:

P0158 Bank 2 Senseor 2 Voltage Stuck High

Went with the obvious and easiest and replaced the oxyegen sensor hoping it was just a bad sensor...

A day later the check engine light was on again, and then 2 starts later it was gone.

If it's not a bad sensor anyone have an idea what would make it draw that kind of voltage.

Thanks in advance,

Same problem here - a 2007 SXT with 3.5L engine.

Was a computer problem. They erased the memory, reflashed it, and all is well so far, for 2 days now.

 

Same here with the P0158 after replacing the sensor - mine is an '05 sxt 3.5L

Is the flasing the fix?
