I have a 1998 dodge caravan 3.3L fault codes p0500 p0700 p0720 p0715, how do I repair and replace sensors to pass smog test

Follow the links for each fault code.
P0700 Transmission Control System Malfunction
P0720 Output Speed Sensor Circuit Malfunction
P0715 sets when there is an error in the transmission's input speed sensor signal. On the front of the trans there is an input and output speed sensor that the trans controller looks at for shifting control.

While the code could have set because of a wiring or connection problem, it's almost surely the sensor. Input speed sensor failures are not uncommon.

The input speed sensor is mounted right on the front of the trans directly under where the cooler lines attach. It threads directly in and has a 1" hex for a socket for removal. If the wiring and connection look visibly ok then I would recommend replacing the sensor

Why won't Rad fan run if fan motor, fan relay, temp sender all okay?

check terminals on the ECM
the circuit is when the coolant temp sensor ( not the gauge sender) reaches a predetermined setting , power is supplied to the ECM which in turn activates the fan relay and switches on the fan
there are normally 2 fuses in the circuit
the gauge sender is normally a single wire unit and the sensor unit has 4 wires to it

Radiator fans do not work on my 1997 chevy malibu

There is a sensor on the top of the engine which turns the fans on. it is usually located near the thermostat housing but dont confuse it with the temperature sensor which can easily be tested in the same means by watching the temperature gauge as you ground it out. it may take several seconds to indicate it on your sensors.
If you by-pass and hook the fans up direct without an in-line fuse and there is resistance in the line from a bad fan motor you will melt the wires and the fan motor itself. Use a 30 or 40 amp fuse inline and put on a switch if you like but don't hook direct but only for a few seconds or so to see if is working well. Use very thick wire like booster cable wire.

Take the lead off the sensor and contact it to the ground on the engine. If the fans start up with car running even cold then replace this sensor.
If not check relay by switching with same numbered relays typical in most vehicles. Mark the original relay and note it's position, take pics if you like to aid in placement.

Good luck!

Does a 1996 Ford Taurus 3.0 have a hot wire type mass air flow sensor or a vane type? Would spraying carb cleaner into the MAF fix the problem of hard cold engine start? Once the engine warms up does the...

TheMobilian, Yes, the Mass Air Flow is a Hot Wire type. There is a spray made for the mass called mas air flow cleaner. Regular cab cleaner is too harsh and can eat the coating inside mass air flow and it's delicate parts. Use throttle bore foam cleaner; it works like bathroom scrubbing bubbles and eats the gum and varnish. When engine warms up (closed Loop) both sensors work together giving input to ecm for output. Have someone with a live data reader read both sensors. (Let me know the readings?)

Image Mass Air Flow(MAF)Sensor


The Mas s Air flow (MAT) sensor measure s the amount of air flowing into the engine.

This value is used by the Powertrain Control Module (PCM) in calculating the required

Fuel injector pulse within order to provide the desired air fuel ratio. This input can also

be used in determining Electronic Pressure Control (EPC). Shift and torque converter

clutch scheduling.


The MAE sensor is located directly in the airflow path between the air cleaner housing

and the throttle body. Ail air entering the intake manifold must pass through the sensor.

Located in the MAT sensor directly in the airstream are two platinum wires, a hot wire

heated by electrical current and a cold reference wire. The MAF sensor uses the air flow

across these wires to calculate its output.


The hot wire is maintained at 200CC (392CF) above ambient temperature as measured by

a constant cold *e. The current required to maintain the temperature of the hot wire is

proportional to the air mass flow. The MAE sensor then measures the amount of

electrical current required to maintain this temperature difference and converts this

value to an analog DC voltage. This output varies directly with the mass air flow rate.

Pay attention to the Paragraph about the torq converter.

Pass Lock sensor is preventing the car from starting. You need to override it. I used a remote start module. Having this installed bypasses the pass lock sensor.

Security system

There is a way to do this with a resistor I donot know how but you can do it with security bypass module for a remote start system. You can purchase these any where that sell remote starts. Follow the directions for installing the module but on the wire it tells you to hook to the remote start, ground it or hook to a key on ground if you can find one. Any questions please ask.

1994 Chrysler LHS engine won't turn over.

I checked another site that had a possible solution. It told how to check the ignition switch. After performing this check I decided to replace it. Still no go. The only other thing I could think of was possibly a loose or broken wire somewhere. After looking it over I decided that tracing the wires would be too much trouble.

My solution was to by a remote push button starter switch. I'd just run a wire from the battery to the switch and from the switch to the starter. As of this writing I'm still in the process of installing it. I did manage to "hot wire" the starter and it started fine. That's what lead me to believe the problem is in the wiring. So this remote switch should work.
