Archived Complete Loss of Power

[tmurray]

The truck was running fine even after a few trips in to town. On the last trip I parked it went in to the hardware store. After about 10 min. I stared it up again. It was running rough and rpm’s were going up and down about 200 rpm’s. I have very little throttle response.



I disconnected the EZ and that made no difference.



The codes I got are as following



P0236 (M) Map Sensor Too High Too Long Problem detected in turbocharger wastegate



P0743 (M) Torque Converter Clutch Solenoid/

Trans Relay Circuits

An open or shorted condition detected in the torque

converter part throttle unlock solenoid control circuit (3 or

4-speed auto. trans. only).



P0236 (M) Map Sensor Too High Too Long Problem detected in turbocharger wastegate.

P0753 (M) Trans 3-4 Shift Sol/Trans Relay

Circuits

An open or shorted condition detected in the transmission

2-4 shift solenoid circuit (4-speed auto. trans. only).





P1693 (M) DTC Detected in Companion Module A fault has been generated in the companion engine

control module.

Not sure which one applies

P1693 (M) DTC Detected in PCM/ECM or DTC

Detected in ECM

A 9Companion DTC9 was set in both the ECM and PCM.





P1765 (M) Trans 12 Volt Supply Relay Ctrl

Circuit

Current state of solenoid output port is different than

expected (4-speed auto. trans. only).

Any help would be appreciated



Thanks

Check all the grounds on the truck for clean, tight connections. Clean and add dielectric grease on the battery terminals. While batteries disconnected, turn key on and let 45 minutes pass before trying to restart. don't forget to calibrate the TPPS on the first "key on" sequence (slowly down to floor, release slowly. key off... . ).



Then restart it and have the codes cleared at AutoZone or elsewhere. I'll send along a prayer that it works for you.

I tried all of that and it still as no power.

The odd thing is the fuel pressure.

I have 2 pumps in series. Normally my pressure is 27 psi

Now it reads 7 psi or zero. My fuel pressure is not consistant????

Just posted elsewhere, your speed sensor on drivers side tail of OD unit. Screws in, get at Autozone for $13. 00 with life time warranty. Does not throw any codes and will drive you crazy. They go bad about every 60,000 miles or so. Change quick as trans fluid will drip out when removed. I think it is a one inch socket.
