P0736 P1792 - 2000 Dodge Grand Caravan

Engine coolant temperature circuit low voltage

P0736 is reverse incorrect gear ratio
U0167 is Lost communication with vehicle immobilizer control module

this obd2 trouble code table can help you understand the meaning of code.

for p0736, try:
Start by inspecting the transmission fluid level and condition, and change fluid if necessary.

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

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...

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

Problem internally with transmission

P1792;

It's Either / OR; IF your car have those systems:
Powertrain - Manufacturer Controlled DTC - Manufacturer Controlled;
AT - engine control module (ECM)
OR;
ECM to TCM Engine Coolant Signal (4L30-E Transmission),
OR;
AT - AT EEPROM checksum error
OR;
Barometric pressure (BARO) sensor - circuit malfunction

Caused by your
ECM/Programming
OR;
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.

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..
