 Subject: o2 sensor/computer prob?
IP: Logged
Message:
Am I going crazy? I put a Jet Performance stage 2 chip in my Dakota and
everything was going well till my ck engine light came on. I pulled the
chip, reset the computer and the light went out for a while. Then she
popped back on with 0031, 0051, 0141, 0161... all 4 o2 sensors! Well, I
drive a lot and though it's a 2001, I have 79k miles. I thought what the
heck so I replaced the Bank2, sensor2 and the 0161 went away. So I did
the bank1, sensor2 and the 0141 went away. I drove a while cause the
sensors ain't cheap! Checked the codes again after about 1k miles...
still 0031 & 0051. Got the cash together and replaced bank1, sensor1 &
bank2, sensor1. Reset and everything was great, no light, no codes, just
smooth sailing... for about 5 miles! Then sure enough the ck engine light
came back on and is reading the 0141 & 0161 codes for the first two
sensors I replaced. What's going on here? Is my computer fried from the
performance chip that I never even put back in? How can I be cooking o2
sensors like this? I know I put them in correctly, I know how to reset
the computer. Has anyone ever had this problem? Does anyone have any
ideas?

Check the ground by the coil. I have a '01 Dakota that started kicking the P0141 and P0161 codes. After checking the fuzes, relays and replacing the 2/2 sensor I checked the ground. It looked secure but I was able to get 2-3 turns on the nut holding the grounds to the engine block and I'm 700 mi. with no mil light. Hope this helps
