another code to the list..p0174
I'm still battling with my CEL light.
Here's an update:
replace ALL 4 O2 sensors again (under warranty) which did not change anything
I also NOW am getting the code 0174.
I've been driving around with the OBD scanner plugged in. I've cleared the codes a number of times, and have noticed that BEFORE the CEL light comes on, I am getting (almost instantly) the code p0150, the CEL light comes on after about 10-15 miles. The other code register after about 30miles. Today, the new code is p0174....
Here are all the codes I have:
p0135
p0144
p0150
p0155
p0160
p0174
I have noticed that the LR has not been idling very smoothly either. I"m stumped and not sure where to turn next.
I AM going to get some MAF cleaner and try that.
Thanks,
Steve
PS Is the MAF the same on a 99,00,01,02 AS it is on a 03,04? What i"M finding on ebay for sensors, they are saying they are not.

Dear Steve,
The codes point to the wiring harness to the O2 sensors having a fault. I have used this web site to trouble shoot codes and the steps are helpful.
Your codes and possible solutions are in the site (add each code in upper right corner).

They are...I did check that.
I just went and put my multi-meter on B2 S1 to check the voltage, and this is what I got (and how I set it up)
Putting the BLACK lead to the negative on the battery and the RED to the O2 plug:
Brown - 12
White - 0
Red - 0
Blue - 0
Putting the RED lead to the postitive on the battery and BLACK to the O2 plug:
Brown - 0
White -12
Red - 12
Blue -12
NOt sure if I did the correctly OR if I should have (from what it appears) 3 grounds....
I'm also sure I may not have set the multi-meter correctly to do this test....
