I have a 2003 dodge ram with a 4.7. I am getting code p0335 crankshaft position sensor A.

P0335 = Crankshaft position (CKP) sensor - circuit malfunction.
There is an issue with the Crankshaft position sensor or the wiring to it. Get a Good Auto electrician to test the circuit and see how much it will cost to change the actual sensor.

code p 0335 refers to crankshaft position (CKP) sensor---circuit malfunction=== causes --wiring--CKP sensor ---ECM
at this point because you were in the area doing repairs to the power steering pump , it is possible that you have disconnected the wires to the CKP
check that or replace the CKP

This answer covers 1999-2005 Cadillac Deville, Eldorado & Seville.
Example Engine:
2002 Cadillac Seville STS 4.6L SFI DOHC HO 8cyl.

This engine has (2) Crankshaft Position (CKP) Sensors: the Upper sensor is CKP sensor B, and the lower sensor is CKP sensor A (this is included for the OBD-II DTC codes - P0385 references Sensor B = upper CKP sensor, whereas P0335 references the lower CKP sensor (sensor A)).

Both crankshaft position sensors are located in the front of the engine just above the oil filter adapter. To access both CKP sensors, jack up vehicle on the passenger side, remove the oil filter, and the oil filter adapter, including the Engine Oil Pressure (EOP) switch. See illustration.

The ARROW points toward Front of Car.
1. Upper Crankshaft Position Sensor (B).
2. Lower Crankshaft Position Sensor (A)
3. Engine Oil Pressure (EOP) switch
4. Engine Oil Level switch
The Oil Filter is the can-type object below the oil filter adapter, which includes the EOP switch. Recommend: remove oil filter with an oil filter socket/strap wrench, since it's close to the oil pan.

Error Code: P0335
Description:
Crankshaft Position (CKP) Sensor - Circuit Malfunction
Possible Cause:
Wiring.
Crankshaft position (CKP) sensor.
Engine control module (ECM).

code p0335 refers to crankshaft position sensor ( CKP)-circuit malfunction === causes --wiring---CKP sensor---ECM Replace the sensor.

DTC P0335 - Crankshaft Position Sensor A Circuit Malfunction
The crankshaft position sensor (CKP) measures crankshaft location and relays this information to the PCM (Powertrain Control Module). Depending on the vehicle, the PCM uses this crankshaft position information to time the spark properly or on some systems it is only for misfire detection and does not control spark timing. The CKP sensor is stationary and works in harmony with a reluctor ring (or toothed ring) that is attached to the crankshaft. As this reluctor ring passes in front of the CKP sensor, the magnetic field created by the CKP sensor is interrupted and this creates a square wave voltage signal that the PCM interprets as crankshaft position. If the PCM detects that there are no crankshaft pulses or if it sees a problem with the pulses on the output circuit, P0335 will set.

A P0335 "check engine light" code could be caused by:
Damaged CKP sensor connector
Damaged reluctor ring (missing teeth or not turning due to sheared-off keyway)
Sensor output open
Sensor output shorted to ground
Sensor output shorted to voltage
Failed crank sensor
Broken timing belt
Failed PCM

Make sure your crankshaft sensor is plugged in or replace the sensor if the plug is good.

Hi, these codes relate to the crankshaft position sensor. Recommend you check the sensor to make sure it is tight and the connector is fully on. If it looks in order, consider replacing the sensor. If you reply with your model and year, I will see if I can provide additional information.
