Hi my name is***** with me while I pull up these codes.
PID 91 Percent Accelerator Pedal Position ... FMI 2 Data Erratic Check the TPS and wiring for problems. Possible faulty sensor or wiring
CODE REASON EFFECT
Fault Code: 364
PID: P1689, S233
No communications or invalid data transfer rate detected on datalink between the ECM and VP44 fuel pump control module at pins 4 and 13 of the engine harness.
When troubleshooting for this fault, suspect that one or a combination of the following can be the cause: The ECM, fuel pump, or wiring harness/fuses/relay. remove the vp44 harness from the fuel pump run a separate wire to the fuel pump pin 7 (on the pump)for 12 v power to the batt and run a ground to pin 6 to ground and if the engine starts than you have a electrical issue. If no start your pump is bad.the pic is for reference only ....don't apply power to the harness but to the pins IN THE PUMP
Pump to ECM pinout
What symptoms are you having with these codes?
Fault Code: 283
FMI: 3 or 4
High voltage detected at main engine speed sensor voltage supply pin 8 of the engine harness.
The engine control module (ECM) will use the fuel pump speed signal as a backup. Possible white smoke, hard start, and power derate.
The engine speed sensor provides engine speed information to the electronic control module (ECM). The sensor must be powered up by +5 VDC to operate. The sensor generates its signals by sensing the movement of target teeth cast into a tone wheel that is mounted to the crankshaft. The tone wheel has 35 teeth and a gap where the 36th tooth would be placed. This missing tooth indicates that cylinder No. 1 (and No. 6) is at top dead center.see below
Fault Code: 234
Engine speed signal indicates engine speed has exceeded the overspeed limit.
Fuel to the injectors disabled until the engine speed falls below the overspeed limit
The accelerator position sensor is attached to the accelerator pedal. The accelerator position sensor sends a signal to the electronic control module (ECM) when the driver pushes on the accelerator pedal. The accelerator position circuit contains three wires: a +5-VDC supply wire (pin 29), a return ground (pin 19), and a signal wire (pin 30).
Fault Code: 131
FMI: 3 or 4
High voltage detected at accelerator position signal pin 30 of the OEM harness.
Engine idles when idle validation switch indicates idle and ramps up to at a default set speed when the idle validation switch indicates off-idle.
This fault code will also cause a fuel derate. This could be the cause of a low-power complaint. Also, this fault code can cause starting problems in cold weather.See below
Fault Code: 115
No engine speed signal detected at pin 17 of the engine harness.
Engine power derate.
Possible white smoke
This fault is set when the fuel-metering solenoid valve is energized continuously or if current is detected at the fuel control solenoid while the pump incremental angle sensor detects the synchronization gap of the fuel pump tone wheel. Voltage irregularities and electrical noise can trigger Fault Code 361. Check for low battery voltage or loose pins (pins 6 and 7 of the pump harness connector)
Please take a moment to rate as that is how the site credits my time helping on the site or let me know if you need more help. 5 star and bonuses are always greatly appreciated.
Pleasure to help
It would be the Throttle position sensor and is attached to the throttle pedal in the cab
Thanks for the update. If the sensor and harness are good there could be a software related issue in the ECM requiring reflash, reprogramming and updating. Try recalibration: Key on, press the throttle pedal to the floor and back up 3 times slowly and then see if the problem resolves. If not try updating the ECM software. Let me know
