Replace the TPS. Verify the wiring to it is good, and its making good contact. Check at the PCM side as well.

 

HeyYou,

I really appreciate your help to troubleshoot my truck issues. My wife is a psychologist so she helps me trouble shoot my other issues.

I have tried many things and still having the same problem. there is the P0306 code pending but not stored.

I cleared the codes again after taking the freeze frame data (below)

FUEL SYSTEM 1 STATUS CL
FUEL SYSTEM 2 STATUS CL
CALCULATED LOAD VALUE 20.4%
ENG COOLANT TEMP 68C
SHORT TERM FUEL TRIM BANK 1 +9.4%
LONG TERM FUEL TRIM BANK 1 -19.5%
SHORT TERM FUEL TRIM BANK 2 +2.3%
LONG TERM FUEL TRIM BANK 2 +28.1%
INTAKE MANIFOLD ABSOLUTE PRESSURE 28.0kPa
ENGINE RPM 295/MIN
VEHICLE SPEED 25km/h
IGN TIMING ADVANCE FOR #1 CYLINDER 30.0
INTAKE AIR TEMP 35C
ABSOLUTE THROTTLE POSITION 12.2%
AUX INPUT STATUS OFF

New TPS, checked connectors and harness, reset PCM, removed LTFT data and codes cleared and drivenToday

DTC that caused freeze frame P0306
FUEL SYSTEM 1 STATUS CL
FUEL SYSTEM 2 STATUS CL
CALCULATED LOAD VALUE 92.25
ENG COOLANT TEMP 87C
SHORT TERM FUEL TRIM BANK 1 11.7%
LONG NTERM FUEL TRIM BANK 1 0.0%
SHORT TERM FUEL TRIM BANK 2 -6.3
LONG TERM FUEL TRIM BANK 2 0.0%
INTAKE MANIFOLD ABSOLUTE PRESSURE 94.0 kPa
ENGINE RPM 753/MIN
VEHICLE SPEED 66 km/h
IGN TIMING ADVANCE FOR #1 CYLINDER 15.0
INTAKE AIR TEMP 32C
ABSOLUTE THROTTLE POSITION 54.1%
AUX INPUT STATUS OFF

 

Ok, that's interesting...... In the first set of data, PCM is adding a LOT of fuel to bank 2..... and taking a way a bunch from bank 1. That's not right. How old are the O2 sensors?

In the second set of data, things look only slightly better.... One thing that concerns me is 753RPM at 66km/h??? Really? And at half throttle????

 

The O2 sensors are older than 2 years (I do not know when they were replaced before we bought the vehicle.

Why are there values over 12700% for the 1/1 and 2/1 long term adap?
When I accelerate the value for the 1/1 long term adap goes to 0% and the others remain as they were.

2/1 long term adap 12761.778%
2/1 short term adap between -4% to 5%
1/1 long term adap 12766.26% (*goes to 0% when accelerating)
1/1 short term adao between -4% to 5%

spark advance 24 degree
minimum TPS 0.61V
TPS calculated volt 1.04V
TPS percent 15.07%
TPS volts 1.70V

 

That is just bizarre....... Reset the PCM, drive it for a bit. See what the numbers do.

 

These maybe hard to sort through but is there anything that catches your eye that I can capture specifically?
various drives 0-50 mph

 

Pictures are a bit small for me to be able to read..... My eyes suck.

 

 

I am trying to share some video but not sure if it will work.

 

If you need to you can upload them to Youtube and attach the links.
