If the engine is getting too little fuel it can cause a lean condition, which raises combustion temperatures and, in turn, raises exhaust temperatures. It has been diagnosed with the following codes: PO 400, PO 132, PO 152, PO 158, PO 328, PO 183, PO 463. Search our full catalog of aftermarket Hyundai Fuel Temperature Sensor products below.

On the other hand, a poor fuel temperature sensor leads to stalling, decreased power, and fuel efficiency. I was wondering if anybody could tell me where the sensor is located (I thought fuel pump) and if it is hard to replace.
If this is the case, it's best to visit a mechanic urgently. If the PCM connector does not have a reference voltage, use a multimeter to check the parallel circuits. I trust that since that has been taken care of the po420 code shouldn't come up anymore. The PCM checks the fuel temperature sensor signal on a regular basis and compares the resistance to predetermined values. Ensure that the Fuel Temperature Sensor's connector has a reference voltage and a ground connection, using a digital multimeter (FTS). 0L listing a P0183 code (Fuel temp sensor circut). Mostly, it's because of the overexposure of the car to extreme temperatures. It might differ depending on the brand and make of the car. Damaged, burnt, or corroded wiring and connectors will need to be repaired or replaced. Beware of a bad fuel temperature sensor because it tends to send false signals to the computer, throwing off the fuel and timing calculations.
There are a variety of temperature sensors on different vehicles and fuels, so it's important to follow the manufacturer's recommended testing procedures. If fuel temperature appears much higher than ambient temperature, a P0183 code will be stored and a malfunction indicator lamp (MIL) may be illuminated. If the ECM detects a fault, it may alter the vehicle's fuel pressure or fuel injection. Symptoms of Bad Fuel Temperature Sensor. Fuel composition sensor operation is normally accomplished with a five-volt reference signal and a ground. Preferably, the fuel temperature should be lower than 40°C. However, get it checked by a professional technician because this could not be the case always, as cars become less fuel-efficient with time. It's in the tank, there is a couple page diagnostic procedure in the FSM on how to check it "EC" section starts on page 158 of the 1997 FSM: __________________.

Think of it like this: a higher ratio of fuel is required to cool the engine's temperature so if the ECT is reporting a cool temperature when the engine is warm or hot, the car will need more fuel than needed. It allows adjusting the fuel-injected amount into the cylinder. The amount of ethanol present in the fuel is typically categorized independently of other contaminants. The check engine light on the dashboard turns on almost every time the fuel temperature sensor is making issues, is failing, or has failed. A bad ambient temperature sensor. Do you know how important it is to manage and monitor the temperature of the fuel injection system?
It's the most common symptom. The fuel pump is most likely OK; it's just that the sensor is not sold separately. Were you still throwing the fuel temp sensor code? The spade terminal was corroded off on mine but I just left it as-is without any problems, even though the computer kept throwin a code. It reads the fuel temperature to determine whether or not to raise the fuel pressure using the PRVR Solenoid. The fuel consumption is so high I always need to top up daily. 2014 Nissan Versa Note 1.
If the fuel temperature reflected by the waveform voltage patterns fails to coincide with that of the thermometer, suspect that the fuel temperature sensor is defective. Fuel Temperature Sensor.
