Hello,

My check engine light was on, and I had the codes pulled and they showed the sensor 1 bank 1 o2 sensor not working. I purchased the sensor installed it and the check engine light cleared. I thought cool that was the problem. I drove my truck for several hours that day. The next day I started up the truck and about 30 minutes later the check engine light back on. Bank 1 sensor 2 and bank 2 sensor 1 too rich. So, I purchased the other 3 thinking I would just replace them all. Cleared the codes and drove around for a while running errands. Not issues, my truck set over the Christmas holiday 3 day without starting. Now I have these codes. P0030, P0036, p0131, p0135, p0137, p0141, p219a. When I got it started it smelled like gas and it has a rough idle.

What would cause these codes all at one time? Yes, this is my question.

Hello, these are all Oxygen sensor heater circuit codes. What brand sensor did you put in for the first one?

These codes are all caused by the heater circuits for both Bank 1 02 sensors, I would check the resistance of the Bank 1 Sensor 1 you installed first. If the heaters are not working the sensors will not work correctly. The heater is the 2 wires of the Bank 1 and 2 oxygen sensor 1 is a pink power feed. So, with the key on you should have battery power on the pink wire of both front 02s. They are both powered by the same fuse according to the OEM diagrams. So, I don't think it's a fuse issue. But I'll post the wiring diagrams for them all.
But check for power anyway, The P219A code is a Fuel Trim Code for Bank 1, that's due to the 02 sensor issues. This seems to be all confined to one side of the engine. So, check the connectors and wiring for both Bank 1 sensors.
What was the original code that set for the B1S1?

I can’t find the original code number, but it said o2 sensor bank 1 sensor 1 too rich and something about time delay.

These are the OEM 02 wiring diagrams, it might be that the Bank 1 sensors are having connector issues or melted wires on the exhaust. With both sensors setting low voltage codes, that's why you're smelling gas, the 02 sensors are sending skewed data and the PCM is enriching the mixture on Bank 1 due to the low voltage reading.
The time delay is the switching frequency of the sensor being too slow.
The codes are setting on the heater circuits due to too much current flow or not enough that is being monitored on the heater control circuit inside the PCM. If it was a short to ground it would blow the fuse and codes for Bank 2 would set as well, so it has to be an open circuit or high resistance for the Bank 1 sensors.
The 3rd diagram shows checking power and resistance of the heater check.

Thank you, I will look at this in the morning. It is getting a little hard to start first thing in the morning would this be caused by this as well?

The Bank 1 side of the engine may be flooding out, I wouldnt drive it until you get this resolved or you can damage the Catalytic Converter for that side. Overly rich mixture will melt down the converter and restrict the exhaust. When the 02s read low voltage, thats sending a lean signal to the ECM/PCM and it is compensating for that by overly enriching the mixture. Make sure you unplug both Bank 1 sensors, and check the resistance of each, after you check for 12v feeds. You can compare the resistance reading to the Bank 2 sensors. The Oxygen sensors may change wire colors after the connectors, so they may be the same color at the sensor. Usually they are 2 white wires at the sensor.

Hopefully the Cat on Bank 1 is not already damaged, that's a possibility.

I will say this when the engine is below operating temperature it idles rough but once it reaches 210 it idles fine. When I drove it today on some errands (highway driving) it seemed to have normal power. But since you have said not to drive it until I get this issue fixed, I won’t drive it. Thank you again for the help.

Okay, I just don't want to see a very expensive Cat go bad.
Check these fuses as well, make sure they're not blown, and both have 12-volts.

Happy New Year to you, I finally had a chance to look and my truck today. Here is what I found, I checked the fuse for the o2 sensor for bank 1 and it was good. I checked power going across the fuse with key on 12 volts spot on. So I moved down to the sensor itself and checked with my fluke meter to see if the heater was good and I found that the heater was open on both sensors 1 and 2 so I took those sensors out and took them back to the parts store and exchanged them. I installed them stared up my truck and let it get up operating temperature and the truck is running good. No rough idle or miss. Thank you for the help.

Okay, cool, glad that was an easy fix, sounds like some bad aftermarket parts. That happens a lot, I always recommend the OEM parts when it comes to sensors and engine timing components since they're so important. Hopefully the other ones don't prematurely fail.
