I cant get my wife's 2000 durango 4wd, 4.7 v8 to pass emission test, and with my own scan tool, keep getting PO132, replaced one sensor last year to pass test, now replaced other sensor, both with Autozone sensors, and I think a dealer sensor or two will cure my problems, but not sure? I hate to buy both sensors right now, but don't know which is bad? the readout on it was PO132 MOD $D1 O2S Ckt High Volts 1 1 I have entire readout also. Thanks to anyone who can help!!!

 

well on the 4.7 you have 4 O2 sensors,

src:https://dodgeforum.com/forum/1st-gen...ine-light.html

so the 1/1 is bank one sensor one, i believe that is driverside, precat sensor is shorted out, did you try clearing the code and seeing if it comes back? it could just be water in the connector causing it (ask me how i know )

and yes whenever you replace O2 sensors you should use OEM plug and play sensors, as well as resetting the computer (can also be found at the top of the code index)

 

Welcome to DF
Also ck the power steering switch for any leakage. This will also cause the o2 sensors to fail too.

 

SHRPSTR325, did the resetting steps and sent wife off to work, and check eng lite came back on, but didn't you say it would take 12 -50 starts or so, to eventually make that go away, or is this an indication that something is still wrong? Also the dealer parts dept could only account for two o2 sensors instead of 4 on the 4.7? MASTER TECH, how would the power steering switch leaking affect the o2 sensor? Thanks for the quick response to everyone!!

 

Power steering switch can leak and the dripping fluid can get onto the sensor causing a dirty connection issue.

You have 4 - 02 sensors on a 4.7L so find a new dealership unless you have a 5.9L by mistake?????

Take the 02 sensor out and with a propane torch burn off the carbon off the end and re-install or simply take it back under warranty. I have seen MANY issues with replacement 02 sensors form auto parts warehouses. The dealership 02 sensors are the best hand down.


P0132 1/1 O2S Shorted To Voltage


Also being this code I would assume you don't have a 4.7L so please advise?

It is a short not Hi voltage. I don't know where you got that code but it is wrong.

 

Wow, you really do hate everyone equally, I can relate. If there's 4 02 sensors the state of ga. doesn't know about them so could you enlighten me on where they are??I would be more than happy to email you the state test results that say FAIL dtc1= po132 O2S High Volt (Bank 1 Sensor 1) There was a code for the second sensor I replaced which was P0135, but it went away after installing the new one. The vin # was verified by the dealer as a 4.7 so I'm completely in the dark about what you're saying?? Is it just me or what? Cant seem to get attachments to work on this site so if you want the info please email me @ mblack18@att.net thanks

 

I got all the codes straight from the dealer and these are the most up to date codes available: https://dodgeforum.com/forum/1st-gen...ine-light.html Just for ***** an giggles I will attach the 2000 Durango Service Manual CEL's (from your year truck) which includes these codes.

P0135 1/1 O2S Heater Failure

This is very close failure on the same 02 sensor. It is a short not Hi voltage. I don't know where you got that code but it is wrong. Now does your motor look like this accept for the cool lookin ****?:



To answer your question, on a 4.7L there is 1 of 2 on each bank. A bank is a side. For instance, 1 of 2 on should be on the drivers side pre-CAT 02 sensor and the 2 of 2 would be the after-CAT on the drivers side. 2 of 1 is the passenger side pre-CAT and 2 of 2 is the passenger side after-CAT. So on a 4.7L you should have 1 each 02 sensor on each side before the CAT and 1 on each side after-CAT for a total of 4. On a 5.9L and 5.2L (which in 2000 they stopped making a 5.2L as the 4.7L replaced it) they have only 2 sensors. One pre-CAT after the conjoining "Y" exhaust connection (before the CAT and 1 right after the CAT meaning 1 of 1 and 2 of 2 on the codes. Now you could have a engine swap vehicle.

You are a freakin wizard!! I took three pics , one even of the factory sticker, stating it's a 4.7! WRONG!!!! It's clearly a different engine, but know the question is which one is it? Please help me get the code po132 to go away, now that the tags are officially expired, due to the dumbasses I'm surrounded by here in Georgia!!! Now my wife is twice as pissed so please get back asap so I can get this thing done. 'I can't get the pics to attach so please email me at mblack18@att.net and I'll email them to you. I'm new at this "forum stuff" Thanks again for hangin in there with me!!! Mike

You have a 5.9L with a 46RE transmission. The owner before you swapped the motor or the front clip/hood with a 4.7L.
