2014 Cruze Diesel CEL
Before I buy a sensor, figured I would get some hopeful agreement from the caucus on here.
Car is throwing a MIL and is in DEF poor quality countdown to useless car mode. P20EE is the code, and combined with poor DEF, I am leaning towards buying a N0X #2 sensor for ~190 bucks Ref http://www.rockauto.com/en/moreinfo....0466&jsn=10466 thoughts? |
Do a manual regen on it first. Also review the freeze frame data.
|
Isn't that sensor covered under warranty? I replaced it myself before it was a known problem (I had persistent P11D7). There was a revised part, maybe check the module and compare with the rockauto p/n to see if it was replaced before you go and buy it ?
If you want to do a manual regen or force a normal cycle, check the Google play store for Biscan, it's a torque pro pluggin that allows those functions without a trip to the dealer (they charge quite a bit for that I heard). It also includes several other diesel PIDs. |
Can't you lemon law that car by now? Haven't you had it in the shop more than twice for the same thing in 30 days?

According to this it sure looks like this car is covered. But you have to go to the manufacturer, not the dealer

I will look into the scan tool, would love to avoid the dealer for stupid BS like this |
I can do it with the Autel, haven't tried the snap on yet.
|
Dealer note indicated it was not getting anything from NOx #2, so replaced that sensor.
Topped off DEF tank and still in ****ing countdown mode. Would a manual regen do anything for poor quality DEF countdown? Wish biscan would let you reset countdown mode. :| |
Update: Car is still throwing P20ee and the manual regen did not do anything.
|
Was NOx1 replaced and newest tune flashed?

Honestly already started looking at a fleece tune and saying F it to this crap.

Before I spent any money deleting stuff I'd try the free recall work. If NOX1 is bad and giving false readings, when the PCM compares NOX2 with NOX1 to see if the SCR/DEF is working, it gets an invalid result and thinks the NOX reduction system isn't working.
The new calibration is supposed to help with the false error condition, too. Also, if they do the recall work, the DEF is known good and the DEF injector is working, it points at a bad SCR catalyst, which is an emission system component and covered anyway.

I am going to call the shop my family uses for their vehicles and see his confidence level with this car. That will happen before the tune trigger is pulled. |

What's passenger car diesel inspection for NJ? |
If you're anywhere near me I'd love to take a crack at it. I do more diesel work than I'd like to admit. Just fixed a few countdowns on bluetec Mercedes sprinter vans in the last few weeks, I enjoy a challenge. I've got a 6.4 powerchoke at the shop that I'm doing injectors on tomorrow.
