I show 2 codes P0138 and P1146 and know they are the bank 1 rear sensor 2 (white) and was wondering if any one has used an o2 sim or spark plug foulers in order to get rid of of these codes ?

You can simulate the secondary o2 sensors with an o2 sim

When you go into the 5th gen forum section theres this tab that says Search this forum you click on it and search your codes

P0138 = B1 S2 = Right bank (closest to firewall) Rear sensor
P1146 - Heated Oxygen Sensor 2 Minimum Voltage Monitoring (Bank 1)

yes a simulator should fix this

o2sim works great! i installed mine and bypassed both secondary o2's, even though only 1 was bad.. and its been about 300 miles and the ses light didn't come back

Don't forget that if you want to complete eliminate the secondary o2's, you must use a resistor to fool the ecu to think that there is a heating element present.

I used (2) 10ohm 10watt ceramic resistors in series for each o2 sensor. Total of 4 resistors.

I bought them at Radioshack.
