### My gas gauge in my 2002 Pontiac Bonnivile shows empty all the time

Fuel Gauge Troubleshooting

Fuel Gage
The IPC displays the fuel level as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the fuel level percent. The fuel gage defaults to empty if:
• The PCM detects a malfunction in the fuel level sensor circuit.
• The IPC detects a loss of class 2 communications with the PCM.
When the fuel level is less than a pre-determined value, the CHECK GAGES indicator illuminates.
DTC P0462
The fuel level sensor changes resistance based on fuel level. The PCM monitors the signal circuit of the fuel level sensor in order to determine fuel level. When the fuel tank is full, the sensor resistance is high and the PCM senses a high signal voltage. When the fuel tank is empty, the sensor resistance is low and the PCM senses a low signal voltage. The PCM uses the signal circuit of the fuel level sensor in order to calculate the total remaining fuel (%) in the tank. The PCM sends the fuel level percent via the class 2 serial data circuit to the IPC in order to control the fuel gage. The fuel level information is also used for misfire and EVAP diagnostics

### I have code P0118.wont i may start in just a min,the engine hesitate and going to stop

http://www.obd-codes.com/p0118

What does that mean?

The engine coolant temperature (ECT) sensor is a thermistor screwed into a coolant passage in the cylinder head. Sensor resistance is high when coolant temperature is low and resistance drops when coolant temperature increases. The powertrain control module (PCM) provides a 5 volt reference and a ground to the sensor. The PCM monitors voltage drop to determine coolant temperature. If the ECT reads less than freezing temp. when engine has been running for more than a few minutes, the PCM determines a circuit fault and sets this code. Or if the PCM determines the sensor resistance is out of specs, this code is set.
Potential Symptoms

Symptoms of a P0118 could include:

• Very poor fuel economy
• A no start condition
• Vehicle may start, but run very poorly, blowing black smoke, running very rough and misfiring
• Illumination of MIL
Causes

A code P0118 may mean that one or more of the following has happened:

• A bad connection at the sensor
• An open in the ground circuit between the ECT sensor and the PCM
• A short in the voltage feed between the sensor and the PCM
• A bad PCM (less likely)
• A bad temperature sensor (shorted internally)

### E70 error code on electrolux dryers inspire, it is working but dries the clothes to damp then this code comes up

Hi Nora King - Error code E70, typically means that there is a communication error with the outlet/inlet control thermistor that has an open or short circuit. You will need a certified professional to check the resistance of outlet/inlet control thermistor and check wiring for either short or open circuit.

### What is diagnostic procedures for DTC p0135 & p0141

Oxygen Sensor problems... P0135 (Bank 1, Sensor 1) and P0141 (Bank 1, Sensor 2)

P0135 - Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
This code refers to the front oxygen sensor on Bank 1. The heated circuit in the oxygen sensor decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it.

The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0135.

Symptoms: You will likely notice poor fuel economy the illumination of the MIL.

Causes: A code P0135 may mean that one or more of the following has happened:
O2 Heater element resistance is high
Internal short or open in the heater element
O2 heater circuit wiring high resistance
open or short to ground in the wiring harness

Possible Solutions:
Repair short or open or high resistance in wiring harness or harness connectors
Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)

P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)
This code means that the heated circuit in the oxygen sensor on bank 1 decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0141.

Symptoms: You will likely notice poor fuel economy the illumination of the Check Engine Light.

Causes: A code P0141 may mean that one or more of the following has happened:
open or short to ground in the wiring harness
O2 heater circuit wiring high resistance
O2 heater element resistance is high
Internal short or open in the heater element

Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.

Possible Solutions:
Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
Repair short or open or high resistance in wiring harness or harness connectors

Hope this helps (remember to rate this answer)..

### No power to fuel injectors

Determin if the injector operating:
1. disconnect the injector electrical connector and measure the resistance of each injector with an ohmmeter. Compare the measurement with the resistance value Specifications are 11 to 18 ohms.
2. Replace any injector whose resistance value does not fall within the specifications.
If the injector was not operating but the resistance reading was within specifications, the PCM Powertrain Control Module (PCM) or the circuit to the injector may be faulty.

Check the ignition fuse located in the engine compartment fuse center. Also. check the fuel pump relay.
Note: The fuel pump relay is located behind the radio in the center of the instrument panel.

If the relays are good and the fuel pump does not operate. check the fuel pump circuit. If the wiring and the connectors are
good, replace the fuel pump.
