Hi all.
I just have a 2001 Rodeo 3.2 V6 Two Wheel Drive. It has 113k Miles but runs great.


I have two questions.


1-Check Eng Light is on and Scanner shows only one code (P0300) Bank 2 Sensor 1. Can anybody tell me which is exact location of sensor.??


2-Also ABS light comes on sometimes, and sometimes not. I have chec Pads ans looks in great shape, Any idea why the light comes on sometimes only??


Thank you!!!

 

Ist thing a P0300 is not an o2 sensor code it is a random misfire code, you need to have it ck'd by an Isuzu dealer due to some aftermarket scanners don't tell you all of the codes and give you incorrect info,


On the abs light when at the dealer have them ck the abs system for history codes and see whats in there, If it is a rear speed sensor code have them replace the abs module, On this year the problem is in the module, but on the 98 and 99 modules it was a broken harness at the fuel tank and the drivers side in front of the rear wheel.


What state and city are you in I might know a tech at a dealer close to you

 

On the ck engine light if the code is a p0155 bank 2 sensor 1 it is the drivers side front o2 sensor (in front of the cat)

 

Im sorry guys. My car used to have 2 codes P0300 wich was fixed doing a tune up. and still P0155 Bank 2 Sens 1.


The ABS light just comes on some times for a while and then goes off.


Thank you again!!!

 

replace b2 s1 o2 sensor it will fix the problem, that is a heater circuit code, there is a short inside the o2 heater circuit

 

When I had the same problem with my Porsche which thrown me an OBD II codes P0135 along with P0155... My mechanic told me that </span>both codes are
for heater circuits in the Bank 1, sensor 1 and Bank 2, sensor 1 O2
sensors. </span>It was very
likely that a blown fuse could set both codes. I ask him why did the fuse was blown.. He said that there are a couple possibilities why I was having both code in my Porsche Oxygen sensor. 1. A
malfuntioning heater circuit or 2. A short in the wiring to the o2
heater. Noted that the short in just one of the O2's heater circuits would
set a code for both because both are likely fed off of the same fuse.
So check fuses. If an O2 fuse is blown=check your wiring visually for
shorts. If you find none, then unplug both front sensors and then
install a new fuse. Turn the ignition on. If the fuse doesn't blow
immediately then the problem is in one of the sensors. Now plug in the
sensors, one at a time, checking the fuse in between. When the fuse
blows, the last thing you plugged in is the culprit. Hope this helps... Good luck!!!</span>
