DTC P0183: Fuel Tank Temperature Sensor Circuit High Input <---After getting rid of my Cat Error code the car is still reading an error for this. I had both codes at the same time and i found this one while fixing the cat SES fix. WHat could be causing this problem???

 

The shop manuel has a step by step diagnostic protical for that condition

 

ok well i have the manual right here....


CIRCUIT OPERATION
• 5-volt voltage is applied to the fuel tank temperature sensor output terminal (terminal No. 3) from the ECM (terminal No. 77) via the resistor in the ECM.
• The fuel tank temperature sensor output voltage increases when the resistance increases and decreases when the resistance decreases. The ground terminal (terminal No. 2) is grounded to the vehicle body.
TECHNICAL DESCRIPTION
• The fuel tank temperature sensor converts the fuel tank temperature to a voltage.
• The ECM detects the fuel tank temperature in the fuel tank with this output voltage.
DTC SET CONDITIONS

Check Conditions
2 seconds or more have passed since the starting sequence was completed.

Judgement Criteria
• Fuel tank temperature sensor output voltage has continued to be 4.6 volts or higher for 2 seconds.
TROUBLESHOOTING HINTS (The most likely causes for this code to be set are: )
• Fuel tank temperature sensor failed.
• Open fuel tank temperature sensor circuit, harness damage, or connector damage.
• ECM failed.

Here is a picture....i took the seat off ...no way to get tot he sensor ..is it underneath the car?

 

Did you ever fix the p0183 fuel temperature problem i have the same code erro

 

/\ I hope so after almost six years. :P

hahahaha for reals i didnt even notice its was the long well i hoping he replys and gives me a idea of what could be wrong with my
