P1768 MEAN TRANSMISSION RELAY ALWAYS OFF..WAS UNABLE TO FIND P1792..IF PROBLEM STARTED AFTER HEADS WERE DONE..LOOK CLOSELY AT AT ENGINE MAIN WIRING CONNECTORS AND GROUND CONNECTIONS THAT ARE ON ENGINE..LOOK FOR GROUND EYELETS NOT SECURED OR LOOSE..LOOK FOR ANY PINCHED WIRING AS WELL..MAKE SURE NO SPREAD TERMINALS IN CONNECTORS AS WELL..YOU CAN ALSO TRY SWAPPING ANOTHER RELAY IN PLACE OF TRANS CONTROL RELAY..MAKE SURE PART NUMBERS MATCH UP..
TCM(NGC)PIN 16 IS TRS T3 SENSE CIRCUIT..PIN 17 IS NOT USED...HAS TO DO WITH TRANS RANGE SENSOR..I DON'T THINK THIS CAUSING YOUR PROBLEM..

What are possible causes of P1768 code on a 2001 Chrysler PT Cruiser?


Do the easiest things first:
Check the battery earth lead (bear in mind that if you disconnect the batter you will probably have to re-enter the radio code). Check where it connects to the body/engine block - make sure it is clean and secure.

Then check every other earth lead you can find

What does 2002 chrysler concorde engine code P0846 mean ?


Transmission fluid pressure...If the fluid level is ok the most likely cause is the 2/4 clutch's pressure switch itself. This is located in the solenoid pack mounted to the valve body.The solenoid pack isn't that bad to do on a hoist, but it will be a pain to do on the ground. You have to drop the valve body, which can be tricky and there is the potential for some pretty serious damage if not done correctly. It would take you a few hours to do.

Recently the transmission is Stuck in 3rd


P1768 - Performance / Normal / Winter Mode Input Malfunction

P1733 - 3-4 Shift Malfunction
I would suggest you have the shift solenoid electrically tested to determine if they are at fault here or that you have a wiring issue or a failed Transmission control module. You will need the help of a transmission shop to diagnose this properly, do not just replace parts until you are sure they are the problem.

What is manufacturers code p1792


Hi

Firstly what country are you in? if in the US the OBD codes are diffeernt from the UK but I know both issues regadless.

Normally in the UK the code is for the Engine Coolant Temperature Sensor but I have known people to repair this fault and still have an engine light, normally removing the battery and then reconnectin it 1 hour later does the job " make sure you know your radio code though" also though sometimes you will find the fault is the ECM and you would have to have that programmed at a GM dealer normally thats Vauxhall in the UK.

Get back to me with your country and I will give you further info

95 millinia 2.5L codes p1195,p1522,p1777,p1792 engine bogs down and cuts off randomly i had these codes read but dont know what they mean they are obd1


P1195
Barometric pressure (EGR boost) sensor circuit malfunction
p1522
Variable resonance induction system (VRIS) solenoid valve #2 circuit malfunction
P1777
Torque reduced signal error (ECT sensor)
P1792
Throttle position sensor (TPS) malfunction

Thats a lot of sensors to fail at once i would check out the wire connected to your computer or maybe the computer itself...

Check engin light on. There are four error codes P0137,P0141,P0342, and P1792. How do I fix it. Will I pass inspection with these codes?


P0137 Error code Faulty O2 sensor Exhaust leak near the rear sensor
  • Plugged catalyst
  • Short to voltage on O2 signal circuit
  • High resistance or open on O2 signal circuit
Possible Solutions
  • Replace faulty sensor
  • Repair exhaust leak near the rear sensor
  • Check for restriction in catalyst and replace as necessary
  • Repair short, open, or high resistance on o2 signal circuit
P0141 Error code means Downstr Heated Oxygen Sensor Heater circuit fault - Bank No. 1.

- replacement is needed for this issue.

P0342 Error code means Camshaft Position Sensor Circuit Low Input

P1792 Error code means P1792 means the computer isnt properly programmed so if this code keeps comming back the pcm may need to be replaced

What does the diagnostic code P2181 mean on a Subaru Impreza WRX?


this is a coolant performance code. Usuallly sets this code if the connector was left unhooked to the coolant sensor or the thremostat is stuck open. By any chance do you have a gauge that seems to be on the cold side ??

AT - engine control module (ECM)
OR;

OR;
AT - AT EEPROM checksum error

Caused by your
ECM/Programming

Key on or engine running, then the PCM detected that the ECT sensor signal was below the lower or over the upper limit, or that the ECT signal was unreliable, conditions met for one second

Try it, & PLZ; let me know if I add any benefits to you.
I hope I add some thing valuable to you.

I have a diagnostic trouble codes p1768,po300,and a po420. what does this mean?


I have tow of the three requested codes. po300 is misfire detected at multiple cylinders. See po301-306 represent the cylinder # misfire. So 301 is cylinder #1 misfire.

po420 is Catalytic Converter Efficiency Failure
