Bank 1 sensor 1 on a 5.7 hemi - 2008 Chrysler Aspen

Bank 1 is the side of the engine that #1 cylinder is located and sensor 1 is the one closest to the engine. Sensor 2 is by the catalytic converter.

code p013A refers to heated oxygen sensor (HO2S) 2 bank 1 --slow response to lean====causes -- wiring---HO2S --ECM
I doubt if the code faults are the reason for it not to start unless the problem is in the ECM
more likely the problem is in one of the folowing sensors , idle speed sensor ,
MAF/VAF

no year, no joy 6.4L engine , V8
surely you know that..
post year, post DTC errrors, all errors using a real scan tool
not just the 1 in the dash, or autozoned .

my wild guess is B1S1 fails. bank1 sensor 1 ,
but , with no DTC, posted, i cant tell which of 4 test failed.
so, cant help.
not really.

my guess is this car is a Grand Cherokee.
and is WK model.
2011 to present

the engine line up is

3.6 L Pentastar V6
5.7 L Hemi V8
6.4 L Hemi V8 (SRT-8) bingo?
3.0 L VM Motori A 630 DOHC V6 diesel (nah)

now ill guess, sensor wires are damaged.
on a car this new.
did you even look at B1S1

B1 means bank 1 and is cylinder 1 bank
S1 is front , (called up stream)
gander at it, see it packed in mud, or any damage there at all>?
it must breath, air. so , dust it off if packed in mud.
the wires can be damage, look at it and the connector
for corrosion
if the DTC says bad heater it is bad, or wires cut.

Usually the code means the O2 sensor is faulty.
But in your case it could mean there is a problem with the fuel system on bank two. Bank two is the side with cylinder two.
A low voltage reading from the sensor would mean that side is very lean if the sensor is working and the sensor in front of the catalytic converter shows the same readings.

Depending on what type exhaust you have ( dual or single) you will have several oxygen sensors. The bank # XXXXX means it is one of the o2 sensors on drivers side. The sensors are located screwed directly into the exhaust pipe at different spots. See below. You will have say sensor 1/1 which means sensor 1 / bank 1 etc..



Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Hello! See diagram below of the location of Crankshaft Positioning Sensor (CPS)...It has a 3 wire connector with the following wire colors...Dark Blue/Dark Green (ground)...Dark Blue/White (signal lead)...And Pink/Yellow (+5 volts)...

Looking at the front of the engine...The left bank (front to rear) are 2, 4, 6, 8...
The right bank (front to rear) are 1, 3, 5, 7...Therefore the first cylinder on the right bank is # 1...The rear or last cylinder on the right bank is #7

Hi!!
The O2 sensor for Bank 1 is located below left front of transmission, in exhaust. Check diag. below.


Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

bank one is the cylinder head with number one cylinder and sensor two is the second sensor from the motor.
