2011 Volkswagen Jetta has code P0321 which book says crankshaft position (CKP) sensor/engine speed (RPM) sensor- range or performance problem How do I fix that

Are you sure theses are the codes given? They read as...
P0311 = Cylinder 11 - misfire detected.
P0321 = Crankshaft position (CKP) sensor/engine speed (RPM) sensor - range/performance problem.
The first code appears to be for a 12 cylinder engine, not fitted to the Santa Fe.

P1335 CHEVROLET Description
The Crankshaft Position (CKP) sensor sends pulses to the Powertrain Control Module (PCM) as the reluctor wheel teeth rotate past the CKP sensor. The PCM uses the CKP pulses to synchronize the ignition and fuel injector operation, and to time the interval between each CKP pulse. The PCM determines when an excessive change in crankshaft speed occurs by comparing each new time interval with the previous interval. A misfire causes an unexpected change in the crankshaft speed. A certain amount of acceleration/deceleration is expected between each firing stroke, but if the crankshaft speed changes more than an expected amount, the PCM interprets this as a misfire. The interval between CKP sensor pulses is extremely small. At high engine speeds, slight variations in the following components make misfire detection difficult:
- Crankshaft
- Reluctor wheel
- CKP sensor
The PCM learns variations during the Crankshaft Position System Variation Learning Procedure. The PCM compensates for these variations when performing detect misfire calculations. Only a scan tool can command the PCM to perform the Crankshaft Position System Variation Learning Procedure again.
Perform the learning procedure after the following actions:
- A PCM replacement
- Any operation or repair involving the crankshaft, the CKP sensor, or the CKP sensor to reluctor wheel gap relationship.
- An engine replacement.
- The ignition switch is in the ON position until the battery is drained.

There is no idle sensor on the 2000 Chevrolet Impala, according to my online resource.

But, there is the following that senses rpm of the engine and thus the idle speed when the Throttle Position Sensor is at 5% or the accelerator pedal is not depressed:

Crankshaft Position Sensor Operation Engine speed is a very important input to the Powertrain Control Module (PCM). Crankshaft speed and position are the basis for many calculations made by the computer. Crankshaft position values are transmitted to the computer by pickup coils also known as Permanent Magnet (P/M) generators, Hall Effect sensors or optical sensors. The Crankshaft Position Sensor (CKP) also known as engine speed sensor is typically located in proximity to the crankshaft.
In addition, the PCM uses the CKP sensor in conjunction with the camshaft position sensor to calculate and perform misfire diagnostics.
Related Symptoms

• A No Start / Intermittent Start condition - Can be caused by a faulty crankshaft position sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit.
• Engine Misfire Diagnostic Trouble Codes

NOTE: Engine Mechanical conditions can also create the same or similar symptoms. (Don't overlook basic mechanical integrity).

PO231 is related to the engine speed sensor. It's on the right side of the oil filter.
