Are you sure it was the speed sensor.... speed sensor fail will also affect the abs.... now cam or crank sensor will put engine in limp mode.

remove the front 02sensor and drive the car like that, remove means complety take it apart from exaust, if problem goes away or gets so much better then your catalitic converter at the exaust is restricted and need a new one

this problem could be caused by the mass air flow censor, i had the same problem with my car. it is really pricey at the dealer so you might want to check elsewhere for this part. I found one at a scrap yard for 85% less that the dealer and i also got life time warranty, the dealer does not offer any warranty on this part.

It is possible that this code can be caused by the speedometer head itself. The signal from the speed sensor is processed in the speedometer and then sent to the ECM. Check the two screws on the back of the speedometer to see if they are loose. If so retighten and drive to see if the check engine light comes back on. If they are tight, replace the speedometer assembly( I think you gave to purchase the entire meter assembly). If the light still comes on, which is unlikely, you will need to check the wire going to the ECM.

The engine speed signal code is generated from the crank sensor. The crank sensor is located on the back side of the engine block. See image.

Trouble code P0320 ignition/dist. engine speed input circuit


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

Service engine light and abs senor light will not turn off


Some times the wheel speed sensor will go out on either side. This will make the A.B.S. light come on. But I dont see why the service engine light would come on. I would segest changing all wheel speed sensors and take it for a drive. The A.B.S. light should go out. If the service engine light dose not go out your local auto parts stors can run a diagnostics test to tell you what the light is on for.

Please contact me if your problem presists.

Thanks, Charlie
