P0139 - O2 Sensor 1/2 Slow Response ........... Help

Gents,
Two days ago i wake up later, got the truck and acelerate fast up to 100km/h. Some minutes after y got the engine check light.

Today the mechanic reset the engine check. The code was P0139 related to the O2 sensor.

Any help??????

I have the repair manual, and that manual ask for many things: leak test in the exhaust, verify sensor, and PCM.

Before trying anything...... any advise?????


Regards,
Willy

i just got that same code tonight.
I was thinking it just needed a new O2 sensor, I have seen this code on other cars.
What was your solution?

Well,
After the reset of the alarm, i have no more alarms for this.
The guy at the shop told me that "something" in the fuel could generate an extrange response in the sensor.
1000km more and no more check lights.

I reset the computer too and no cel for 5 days so far. Maybe just a bad day for the sensor. Funny how we both had the same code.
