What does trouble code p0138 on 2001 dodge 1500 mean?
Downstream O2 sensor circuit volts high.Downstream O2 sensor circuit volts high.
You have a 93 Buick Skylark with the 4 cylinder It codes throttle position sensor changed it twice changed idle air sensor and a used throttle body runs worse still codes throttle position sensor?
you have to adjust the tps by loosing the screws and rotating it till it reads 0.50 volts [you need a scanner to do it]
What Voltage does the fuel pump on a 1998 Kia Sephia operate at I have a 1998 Kia Sephia that wont start and I am only getting 2.5 Volts at both the fuel pump and the fuel pump fuse in the fuse box?
Should be 12 volts, check the fuel pump relay and clean the ground wire to the fuel pump. In fact clean all the ground connections on the vehicle.
My 1993 Plymouth Sundance gets 17mpg or 170 miles to a tank - It's a 2.5L and I just changed the head gasket plugs oil and filters - Is this normal because it should be better?
Should be much better than that with normal driving conditions. An oxygen sensor could be faulty. It most likely will be the map sensor, when the map sensor goes bad you may have a lake of performance, bad mileage, inconsistant idle, and spit and sputter at constant speed or all of the above, to test map sensor use a meter (DC) if you get 0 volts or above 4.5 volts it is bad. normal voltage is 1.5 volts at an idle.
How much voltage should a coolant temp sensor have?
2 to 3 volts.
How do you properly test a MAP sensor on a 1995 Honda Civic EX?
Typical Readings: Sensor output voltage range is 0.5 to 4.5 volts. Output voltages between 0.5 and 1.5 volts indicate a high vacuum (low pressure) situation, such as idle or deceleration. Output voltages between 1.5 and 3.0 volts indicate a medium level of vacuum (pressure) such as a cruise or slight acceleration condition. Output voltages between 3.0 and 4.5 volts indicate a low vacuum (high pressure) situation such as hard acceleration or a mechanical failure. Any reading of 0 volts or over 4.5 volts indicates a problem. NOTE: The following procedure tests the MAP sensor only. Inspect the rubber nipple (fitting) from the MAP sensor to the throttle body. Repair as necessary. CAUTION: When testing the MAP sensor, be sure that the harness wires are not damaged by the test meter probes. Test the MAP sensor output voltage at the MAP sensor connector terminal B. With the ignition switch ON, and the engine OFF. Output voltage should be 4 to 5 volts. Test the MAP sensor output voltage at the MAP sensor connector terminal B at a hot, neutral idle speed condition. The voltage should drop to 1.5 to 2.1 volts. Test MAP sensor supply voltage at sensor connector terminal C with the ignition ON. The voltage should be approximately 5 volts (±O.5 V). As always, check the service manual for the proper procedures and specifications for your particular vehicle.
What is OBD II code P0136?
P0137 = O2 sensor circuit low volts (bank 1 sensor 2). Could be a faulty B1 S2 O2 sensor.
Why ecu is sending 12 volts to ect instead of 5 volts?
Not knowing the year, make, model and engine info, could it be your testing the sensor for the temp gauge?
How do you test a 3 wire crank sensor?
check power and proud to sensor harness: then look at output signal on scope At sensor then at ecm.most these sensors will require a five volt reference. if this a three wire sensoshould be hall effect type; producing a square wave that should go 5 volts to zero volts.
What does downstream 02 sensor circuit volts high mean?
The circuit voltage is too high. Could be a failed sensor, wiring short, or PCM problem.
What is trouble code P0118 2000 ram?
engine coolant temp sensor volts too high.
What is Engine code P0158 on a dodge ram?
o2 Sensor Circuit High Volts (Bank2 Sensor2
