How do I fix code 13 engine speed sensor Above 1000 rpm

Link below will tell you the code is a result of the rough running. Use the checklist to find the cause of the rough running and the idle speed should return to normal and the code should disappear.

Trouble Code: P0301

Cylinder No. 1, 2, 3 or 4 Misfire Detected

Trouble Code Conditions: Engine is running; atmospheric pressure, fuel level, battery voltage, engine speed, engine load are above minimal predetermined specifications; the engine is not in fuel cutoff and intake air temperature and coolant temperature are within normal operating ranges; there are no DTCs relating to ECT, CMP, CKP, MAP or IAT Sensor, to Crank rationality, to Crank Sensor Learn invalid, or to System Voltage. If total misfires detected are greater than 7% during the first 1000 rpm, or are over 3% after the first 1000 rpm, or are 25% during any 200 rpm with suspect cylinder misfire counter more than 80% and no other cylinder misfire counters above 80%, this DTC will set. The MIL will flash after first trip occurrence and will be steady after second trip.

Possible Causes:


Fuel system problems existErratic CMP or CKP Sensor signalsIgnition system problems existEngine mechanical problems existPCM has failed

The very first thing you need to do here is have the engine control module scanned for fault codes with an OBD2 fault code reader or scan tool. Once you have the fault codes then you can diagnose the cause by the fault code or codes received.

There are 2 possibilities here:
1.- There may be a problem with the new speed sensor, the electrical wiring between the speed sensor and the PCM, or an internal PCM problem. To see if VSS signal is present at the PCM a scan tool capable of displaying live data is required.

2.- There is a recall action on this model year for erroneous speed sensor signals; the cure is an updated software calibration. If your truck has not yet had the updated calibration installed, you should call your local Dodge dealership with your VIN number and ask the service department to check to see if there are any open recall actions on your vehicle. If the software calibration has not been updated yet, they will perform this procedure free of charge for you. If you do not have the current software calibration in your PCM to correct the VSS issue, you need to have this done before proceeding any further with attempting to diagnose this problem

This sensor is located at the rear of the transmission.

Symptom: P-0720 LOW OUTPUT SPEED SENSOR RPM, ABOVE 15 MPH
When Monitored and Set Condition: P-0720 LOW OUTPUT SPEED SENSOR RPM, ABOVE 15 MPH

When Monitored: Continuously with the key on, engine running, and gear selector not in park or neutral.
Set Condition: This code is set if the vehicle speed (as determined from the vehicle speed sensor), is above 15 MPH, and the output shaft speed is below 60 RPM for 2.6 seconds.

POSSIBLE CAUSES DTC CODE RETURNS:
OUTPUT SPEED SENSOR DEFECTIVE
PARK/NEUTRAL SWITCH CODE PRESENT
OUTPUT SPEED SENSOR GROUND CIRCUIT OPEN
OUTPUT SPEED SENSOR GROUND CIRCUIT SHORT TO GROUND
OUTPUT SPEED SENSOR SIGNAL CIRCUIT OPEN
OUTPUT SPEED SENSOR SIGNAL CIRCUIT SHORT TO GROUND
PCM DEFECTIVE (DRB SHOWS > 60 RPM)
OUTPUT SPEED SENSOR HARNESS OBSERVABLE DEFECT
OUTPUT SPEED SENSOR WIRING HARNESS INTERMITTENT DEFECTIVE

Hope helps.

CODE 13 NO NE IGNITION SIGNAL TO ECM WHEN ENGINE SPEED IS GREATER THAN APPROXIMATELY 1000 RPM. CODE 14 NO IG OR IGF IGNITION SIGNAL TO ECM FROM IGNITER SEVERAL TIMES IN SUCCESSION.

Because you got a misfire on cylinder #1 PO301
A misfire on cylinder #2 PO302
Misfires first 1000 rev PO316
O2 Codes PO 174
Etc,Etc


The LTT, is the result of not learning (yet-thus long term)
what isn't working correctly---Your Engine

Replace bad Coil--which ever is missing
Do not go by the codes,alone ,TEST

The v-8's timing is supposed to be 0 degrees plus or minus 2 degrees and is only adjustable if you have a scanner. A timing light does not work on them.
These engines can be "timed" in the way you are used too.
The distibutor housing holds the cam sensor, The PCM calculates the timing by measuring the crank signal and the cam signal.

What you are seting by turning the distibutor housing is the correlation between the 2 sensors. On the V-6 model, the housing holddown bracket is fixed to the housing so if you return the rotor to the proper position when reinstalling the housing, the engine should be at the correct cam sensor position setting.they did not fix the holddown bracket to the V-8 models, it would have saved a lot of headaches.
To set the correlation between the 2, you will need a scan tool that can read camshaft position offset. With the engine RPM over 1200 adjust the offset too 0 degrees.
TEST PROCEDURE
The ignition timing cannot be adjusted. The distributor may need adjusting to prevent crossfire. To insure proper alignment of the distributor, perform the following:

With the ignition OFF, install a scan tool to the DLC.
Start the engine and bring to normal operating temperature. IMPORTANT: Cam ****** Offset reading will not be accurate below 1000 RPM.
Increase engine speed to 1000 RPM.
Monitor the Cam ****** Offset.
If the Cam ****** indicates a value of 0°+/-2°, the distributor is properly adjusted.
If the Cam ****** does not indicate 0°+/-2°, the distributor must be adjusted.

ADJUSTING PROCEDURE
With the engine OFF, slightly loosen the distributor hold down bolt. IMPORTANT: Cam ****** Offset reading will not be accurate below 1000 RPM.
Start the engine and raise engine speed to 1000 RPM.
Using a scan tool monitor Cam ****** Offset.
Rotate the distributor as follows:
4.1. To compensate for a negative reading, rotate the distributor in the counterclockwise direction.
4.2. To compensate for a positive reading, rotate the distributor in the clockwise direction.

Repeat step 4 until 0°+/-2°, is obtained.
Turn the ignition OFF.
Tighten the distributor hold-down bolt to 3 Nm (25 lb. ft.).
Start the engine, raise engine speed to 1000 RPM and recheck Camshaft ****** Offset.
Thank you for using fixya and good luck.

Your V8 Audi has two necessary sensors that malfunction due to their placement in extreme heat on the lower left side of the engine just inside of the header/down pipe connection. They read the flywheel position for the engines computer ECU. The reference sensor is always suspect, but the speed sensor may need to be changed, as well. The wire connectors to the sensors that sit above the FL suspension can be tested, or just replace both sensors to get some quality time with your V8.

Only 1000-2000 RPM? Does it do that in any gear?
