What causes intermittent break in speedo readings on a 1998 discovery?


Check the wires that go to the transmission to see that you didn't hook them in something

Jsrock516 - what about motor winding readings from 7.1 to 7.3 ohms? This was...


This advice is for Kenmore Elite HE and Whirlpool Duet FRONT LOADER washing machines displaying the "F06" error code. The error is an indication a motor speed problem. You will need to check the following:

- Check the wiring harness. Verify all connections between the Drive Motor, Motor Control Unit (MCU), and Central Control Unit (CCU).

NOTE: The MCU is a circuit board located in the vicinity of the Drive Motor on the bottom rear of the washer. To access the MCU, you will need to remove the back panel of the washer.

NOTE: The CCU is the main computer for the washer and is located behind the wash tub. You will need to remove the top panel to access the CCU. This is accomplished by removing the three screws in the back of the washer that hold the top in place. Once the screws are removed, the top panel will slide back, then lift off.

- Check the Drive Motor. Perform a continuity check of the Drive Motor windings. Remove the connector plug and check across pins 1 to 2, 2 to 3, and 1 to 3. All readings should be approximately 6 ohms. HINT: You can also take this reading by removing connector 2 from the MCU and measuring across pins 1, 2 and 3. If the readings are good, this will also prove the wiring and connector good.

- Check the MCU. The connectors are numbered 1 to 3 (L to R). That is, with the MCU installed, connector 1 is on the bottom, followed by 2 in the middle, and 3 on top.

Connector 1 - is the serial communications link between the MCU and CCU and has three wires. At the opposite end, this will be the 2nd connector from the rear on the left-hand side of the CCU.
Connector 2 - is the link between the MCU and the Drive Motor. Pins 1, 2, and 3 on this connector are the Drive Motor windings. Pins 4 and 5 are for the tachometer.
Connector 3 – is the primary power connector. Pins 1 to 2 should read 120VAC with the door in the locked position. Pin 3 is ground. At the opposite end, this is the 4th connector from the right on the front of the CCU.

NOTE: All the connector pins are numbered R to L.

If your continuity readings are normal for the Drive Motor and you have verified all connectors, replace the MCU.

If any of the Drive Motor windings indicate readings higher that 6 ohms, replace the Drive Motor.

I hope this information is helpful.

Fuel flow intermittent


i would have to say check fuel filter or it culd be a bad fuel pump.

My fuel gage is giving me a false reading on my peugot partner 1.8L van,how can I fix this problem?


The usual reasons for intermittent fuel readings are that a wire is loose from the sending unit in the tank or on top of the tank, the connection is not making good contact. If you are getting no reading and it was intermittent or "false" reading at different levels of gas in the tank, the sender unit in the tank is broken. It needs to be replaced.

Why does my AC blower motor work intermittently?


Had the same problem, You Need a volt meter and need to "Know How to Use It" to fine this one.
Take readings at the motor connector when it is working right and write them down on paper, when it stops working again, take the readings again. If they are the same look toward the motor, if they are different look toward the switch and wiring, again using voltage meter readings, Mine was a connector pin that was now "clicked" in properly.
Intermittent electrical problems can make you feel like your a blind man trying to catch a stray dog.
good luck

P0121 and p0068 on a 2003 dodge ram 1500 replace the throttle position sensor and the idle air sensor at the same time then ran for a week with no problems then the truck started idling up at random then...


P0121 The Throttle position sensor is a potentiometer that measures the amount of throttle opening. As the throttle is opened, the reading (measured in volts) goes up. The powertrain control module (PCM) supplies a 5 Volt reference signal to the throttle position sensor (TPS) and usually a ground also. A general measurement is: at idle = .5 Volts; full throttle = 4.5 Volts. If the PCM detects that the throttle angle is greater or less than it should be for a specific RPM, it will set this code.
Potential Symptoms Symptoms of a P0121 trouble code could include:
  • Malfunction Indicator Lamp (MIL) illumination (Check Engine Light or Service Engine Soon light)
  • Intermittent stumble on acceleration or deceleration
  • Blows black smoke on acceleration
  • No start
Causes A code P0121 may mean that one or more of the following has happened:
  • TPS has intermittent open or short internally
  • Harness is rubbing and causing an open or short in the wiring
  • Bad connection at the TPS
  • Bad PCM (less likely)
  • Water or corrosion in connector or sensor
Possible Solutions 1. If you have access to a scan tool, see what the idle and WOT (wide open throttle) readings are for the TPS. Check if they're close to the specifications mentioned above. If not, then replace the TPS and re-check.

2. Check for an intermittent open or short in the TPS signal. To do that, you can't use a scan tool. You'll need an oscilloscope. The reason is because scan tools take samplings of many different readings over just one or two data lines and can miss an intermittent drop out. Hook up your oscilloscope and watch the signal. It should sweep up and down smoothly with no drop outs or spikes.

3. If no problems were noticed, perform a wiggle test. Do this by wiggling the connector and harness while watching the pattern. Does it drop out? If so, replace TPS and re-check.

4. If you have no TPS signal, check for 5 Volt reference at the connector. If it's present, check the ground circuit for open or shorts.

5. Make sure the signal circuit isn't 12V. It should never have battery voltage. If it does, trace circuit for short to voltage and repair.

6. Look for any water in the connector and replace TPS as necessary.
P0068 Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of power
- Engine rough idle Possible causes - Large vacuum leak
- Leaking air duct system
- Mass Air Flow (MAF) poor electrcial connection
- Manifold Absolute Pressure (MAP) poor electrcial connection
- Faulty Mass Air Flow (MAF) sensor
- Faulty Manifold Absolute Pressure (MAP) sensor
- TP sensor not seated properly.
- Faulty Throttle Position (TP) sensor.
- Dirty throttle body
When is the code detected? The Powertrain Control Module (PCM) monitors operation rationality check by comparing sensed throttle position to mass air flow readings
P0068 DODGE Description The Powertrain Control Module (PCM) monitors a vehicle operation rationality check by comparing Throttle Position (TP) to Mass Air Flow (MAF) readings. If, during a self-test, the comparison of the TP sensor and MAF sensor readings are not consistent with the calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.

Gas gauge does't work properly


this almost always stems from a faulty fuel level sensor in the fuel tank. It's a part of the fuel pump, so you have to replace the whole thing at once in order to fix it. If you have around 100,000 miles on it, you're getting due for a pump anyways, so you may keep this in mind. Symptoms for the fuel sender, will be intermittent readings on the gas gauge, when it reads, it's correct, but when it doesn't, you get a low fuel message and the gauge goes to empty. This may have a tendency to do it when the fuel tank is within a certain level; but not at a fuller or lesser mark.

Wont start till I pull on the cord to make connection.checked cord with volt meter,its o.k.help. stampvs@yahoo.com


If you have unplugged the unit and performed a continuity (resistance) check from the end of the power cord to where it connects to the terminal block at the back of the appliance, then the next logical step is to perform a voltage check of the wall receptacle itself. If the voltage at the receptacle is good, but you are having connectivity issues with the appliance plugged in, the receptacle terminals may have become loose, or you may have a power cord that has a loose or broken wire. This intermittent connectivity can cause the receptacle and/or power cord to heat up and cause a fire. With the appliance unplugged, connect an ohmmeter to either end of the power cord and perform a continuity check. Move the power cord to see if the readings are constant. If you have intermittent resistance readings, you have a bad power cord. If the power cord still checks good, then I would recommend having an electrician check your wall receptacle before using the appliance again. If you still have questions, let me know. I hope this helps you.
