O2 sensor problems Grand Caravn '04
the OE sensor are made by Denso. But Denso unit cost about the same aftermarket or from the dealer. So get it from the dealer, so you can get a guarantee on it. do NOT get it from Ebay, too many counter fit car parts.
What exactly is your car's problem anyway? year, make and model? what's the odometer mileage?
Price on labor charge varies depending on area. Can't tell you what's a fair charge. only dealer and some large shop has these equipment to do software update, because they are expensive tool and require annual subscription fee.

What is the exact code? heater circuit fault or O2 sensor voltage HI/Lo?
If your problem is the PCM software, usually a battery disconnect hard reset will cure the problem a few week to few year.
I have a co-worker that used to work at Texas dealer, he told me because good shop are few and far in between, so they charge a lot due to lack of competition. so... you can call around and ask how much your closest dealer charge, and look for some Indy shop that advertise they specialize in Chrysler and with the right equipment.

NOTE: This bulletin applies to 2005 CS vehicles equipped with a 3.8L engine (sales
code EGH), 2005 RS or 2005 RG vehicles equipped with a 3.3/3.8L engine
(sales code EGA, EGM and EGH).
DISCUSSION:
A new 1/1 O2 sensor (PN 56029085AA) has been introduced on the 3.3/3.8L engines for
the 2005 RS/RG and CS vehicles built after July 8, 2004 (MDH 0708XX). Installing an
incorrect 1/1 O2 sensor will cause a MIL illumination for DTC P0135 - O2 Sensor 1/1
Heater Performance to be set.
The operation of the new O2 sensor has also changed. The new 1/1 O2 sensor runs at
100% duty cycle all the time because the resistance of the heater is higher. Monitoring the
1/1 O2 sensor with the DRBIIIŽ while the vehicle is in the service bay will show 100% duty
cycle, which is normal for this new sensor.code EGH), 2005 RS or 2005 RG vehicles equipped with a 3.3/3.8L engine

Make sure u used the the correct O2 sensor and make sure the PCM software is up to date.
other wise, check connection on O2 sensor, check connector, Ohm out O2 sensor heater circuit per part number supplier above. If all check out good, u probably need a PCM.
And do NOT use bosch sensor. for chrysler, 50% of the time it doesnt work. On imports like Honda and Toyota, 95% of the time it doesnt work.
