My 2000 F150 Has a code of P0320

Here's the Ford discussion on it:
P0320 2000 Ford F150 Ignition Distributor Engine Speed Input Circuit...
It's not an exhaust issue. P0320 means that one of the ignition coils did not get an electrical pulse to make a spark plug spark.

On certain Ford models, one of the underhood wires rubs against an air conditioner tube and chafes through the insulation causing this fault. You can separate the wire and wrap it with electrical tape and use a cable tie to prevent rubbing. Here's a YouTube video which shows an easy way to fix it.

P0320 means that an ignition pulse that's supposed to fire a spark plug was missed. It could be as simple as a chafed wire under the hood. Watch this video:


Ford has some information too:
P0320 2000 Ford F150 Ignition Distributor Engine Speed Input Circuit...

Code 320 is for a problem with the RPM input to the computer, which could be the distributor or the ignition module.

You'll have to figure out if it is a fuel or ignition problem.
Is the check engine light on ? Have you checked for trouble codes ?
Have you replaced the fuel filter and checked fuel pressure ?
It could be a relay, the ignition module, coil, fuel pump, or a list of other things.

P0320 - Ignition / distributor engine speed circuit malfunction

The ignition engine speed sensor input signal to Powertrain Control Module (PCM) or Electronic Control Module (ECM) is continuously monitored. The test fails when the signal indicates that 2 successive erratic profile ignition pickup (PIP) pulses occurred.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- The engine may be harder to start
- The engine may stumble or stall

When is the code detected?
The P0320 code is triggered when 2 successive erratic PIP pulses are detected.

Possible Causes:
- Loose wires/connectors
- Faulty Crank Position Sensors
- Arcing secondary ignition components (coil, wires and plugs)
- Low battery charge
- Powertrain Control Module

Possible Solutions:
- Resecure loose wire or connectors
- If battery charge is low, recharge or replaced battery
- Replaced crank position sensor
- Replaced starter motor


Test it and tell us news.

replace you intake air control (iac) valve right next to the throttle cable end two bolts hold it on and has two wire plug its about three inches long and round. hope this helps you.

Check the TPS switch and make sure there is no broken vacuum line also check for Codes.

Check EGR valve its probably stuck open cause of carbon build up. Check and or replace.
EGR valve controls idle speed.

I have both the codes here showing the possible causes list only...but full solutions VERY extensive....must email....post here allows too small...
