SOURCE: trouble code P1744

Torque Converter Clutch System Stuck in Off Position. I would clear that one and see if it comes back. You would be ok to get a smog test done with this code. Its a transmission code. If it does come back I would take it to a transmission shop and have it checked out further. Thanks for using FixYa!

SOURCE: 2004 Chevy Silverado HD 2500

On many engines with distributor less ignition systems and sequential fuel injection, a camshaft position sensor is used to keep the engine's control module informed about the relative position of the crankshaft. By monitoring cam position (which allows the control module to determine when the intake and exhaust valves are opening and closing), the control module can use the cam position sensor's input along with that from the crankshaft position sensor to determine which cylinder in the engine's firing sequence is approaching top dead center. This information is then used by the engine control module to synchronize the pulsing of sequential fuel injectors so they match the firing order of the engine. On some applications, input from the camshaft position sensor is also required for ignition timing.
The camshaft position sensor may be magnetic or Hall effect, and mounted on the timing cover over the camshaft gear, on the end of the cylinder head in an overhead cam application, or in a special housing that replaces the distributor (in the case of some of the GM applications). Operation and diagnosis is essentially the same as that for a crankshaft position sensor.  

Re  check the wire harness and the sensor installation to the camshaft sensor in Bank #1 which is where the #1 cylinder is. Good luck and hope this adds some light to you question, keep me posted and be glad to help.

SOURCE: how to remove lower ball joint 2001 chevy silverado 2500 hd 4x4

The reason is they are pressed in and you have to press them out with a tool and some have a C clip that has to be removed you can go to schucks or autozone to rent the tool to press out and it has to be pressed back in.

SOURCE: OBD2 TROUBLE CODE P1121 HOW TO FIX OR WHERE TO

P1121 means that the TP (throttle position sensor) does not match what the MAF (mass air flow sensor) reads

the two leading causes for this are the TP or the PCM (powertrain control module)

you will need a professional scan tool to diagnose in detail

04 Chevy silver 2500 HD won't crank. New starter battery checked out good


Check all your fuses and also the starter relay, are you getting power to everything else? Are you hearing the fuel pump spin up when you first turn the key to the on position? If you can borrow or buy a OBD2 /CAN scan tool and check to see if there is any codes for crank sensor, or cam sensor.

Could possibly be your lock clutch converter solenoid that doesn't work correctly .

Best way to know is to check for engine or transmission codes . But you'll need to have an obd2 scanner.

How do you turn off engine light in a 2003 chevy suburban ?


This will require a code reader/scanner. They are from $30-$300.. You just need the cheap one. Just make sure it erases codes, and most do. it is referred to as OBD2 ( On Board Diagnostics).

I changed out the gas cap on my 2007 Chevy silverade 2500 hd check engine went out by next day it was back on. what do i do now?


Hi:
to figure out what is going on with your truck, you need to have someone with an OBD2 scanner read your codes to see what is tripping the light. A gas cap is a usual suspect, but there are hundreds of other things too. Auto parts stores, like Autozone, will usually read your code for free, and tell you what is going on.
