There's talk on here that about the old engine service light. Well, yesterday my engine service light came on along with the emissions service required message.


I checked the error codes and found


P0156 (Error 1)
P0156 P (Error 2)
P0157 P (Error 3)


I cleared them, and will wait to see whether they turn up again.


Thoughts.


Thanks in advance!

Loose gas cap on last fillup?

 

Not likely. I hadn't recently filled the tank with gas.

 

Oxygen sensor, B-2 S-2 out of range, slow response and or heater circuit. You need to monitor it and verify operation. Helps to check other sensor B-1 S-2 to compare reading. Could be sensor or wiring to the sensor.
