Temp sensor


I'm not a 100% but it sounds like your camshaft position sensor went bad then caused the other codes to come up because the camshaft position sensor tells the computer how much gas it needs. So it started a chain reaction with the fuel level sensor, fuel temperature sensor, and knock sensor codes. The Fuel temp. sensor helps the engine to know how much fuel to inject as well depending on the temp. of the fuel. The fuel pressure sensor senses the amount of fuel in the fuel rail by reading the internal pressure of the rail, so that's what leads me to believe that it's your camshaft position sensor. Particularly if that was the first code that came up. Hope this helps you.

P0462 code


P0462 is Fuel Level Sensor Circuit Low Voltage.
Possible causes - Faulty fuel level sensor
- Fuel level sensor harness is open or shorted
- Fuel level sensor circuit poor electrical connection
Low fuel level can trigger this code. Before replacing any parts try filling up the fuel tank and erasing the engine code. If the problem persist it may be necessary to replaced the fuel level sensor.

P1684 - 1683 - 0135 - 0442 - 0455 error codes


P1684
It is not a fault code per say, it only indicates the battery has been disconnected or went dead in the last 50 drive cycles I believe.
P1683
This code refers to the cruise control speed servo power circuit is open or shorted. The power comes through a normally-on contact in the brake light switch. Use a test light or voltmeter to measure the voltage on the yellow wire / red stripe on the switch. If it's there, measure on the dark blue wire / red stripe. If it's missing there, the switch is defective. The voltage should go to 0 volts there when the pedal is pressed.
The rest of the fault codes are as follows.

P0135 - O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 1
Possible causes- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit fuse
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit poor electrical connection
- Faulty Engine Control Module (ECM) Help with thisTech notes The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The control module monitors how long it take the sensor to warm up and start sending an adequate signal. The code is triggered when the sensor is taking too long to warm up. Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors. If the sensor and connector are OK, replacing the O2 Sensor 1 usually takes care of the problem.

P0442 CHRYSLER - Evaporative Emission Control Small Leak Detected.
Possible causes- Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- EVAP canister or fuel tank leaks
- EVAP system hose leaking
- Fuel tank leaking
P0455 CHRYSLER - EVAP System Large Leak.Possible causes- Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- EVAP canister or fuel tank leaks
- EVAP system hose leaking
- Fuel tank leaking Tech notes The P0455 it's a very common code, because the code is set if the gas cap is loose or missing. Start by tighten the gas cap and clearing the code. In most cases the code can be clear by disconnecting the car battery for about 30 minutes.

Could it be that the ecu is wrong


No it is not Catalytic Converter related. Your fuel tank pressure sensor must be disconnected or the wiring to it defective for the evaporative emission system.

Engine light came on. checked for codes, 1129 appeared. can't find the code anywhere. prior to this code, replaced O2 sensor and transmisson was rebuilt . trans was done first and then code 300 came up....



Jeep code 1129:



Possible Causes

  • RESTRICTED FUEL SUPPLY LINE
  • FUEL PUMP INLET STRAINER PLUGGED
  • FUEL PUMP MODULE
  • O2 SIGNAL CIRCUIT
  • O2 RETURN CIRCUIT
  • O2 SENSOR HEATER OPERATION
  • O2 SENSOR
  • MAP SENSOR OPERATION
  • ECT SENSOR OPERATION

What is the codes means po452 and po453


Hi,

The codes indicate a problem with the fuel tank pressure sensor. One code is for no volts, the other is for high volts. Without a scanner hooked up to monitor. I have to go with you have a bad fuel tank pressure sensor. this is an emissions control sensor. the tank is pressurized and the sensor monitors it for leaks etc. the tank must come out as it is mounted on top of fuel pump module

REMOVAL PROCEDURE

  1. Raise the vehicle.
  2. Remove the fuel tank. Refer to Fuel Tank .
  3. Remove the fuel tank vapor pressure sensor electrical connector.
  4. Remove the fuel tank pressure sensor.
INSTALLATION PROCEDURE
  1. Install the fuel tank vapor pressure sensor.
  2. Install the fuel tank vapor pressure sensor electrical connector.
  3. Install the fuel tank. Refer to Fuel Tank .
  4. Lower the vehicle.
Thanks.
