6. CHECK CKP SENSOR (POS) INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT 1. Disconnect ECM harness connector. 2. Check harness continuity between ECM terminal 14 and CKP sensor (POS) terminal 2.continuity should exist. Refer to Wiring Diagram. 3. Also check harness for short to ground and short to power. OK or NG OK >> GO TO 7. NG >> Repair open circuit or short to ground or short to power in harness or connectors. 7. CHECK CRANKSHAFT POSITION SENSOR (POS) Refer to EC-326, "Component Inspection" . OK or NG OK >> GO TO 8. NG >> Replace crankshaft position sensor (POS). 8. CHECK GEAR TOOTH Visually check for chipping signal plate gear tooth. OK or NG OK >> GO TO 9. NG >> Replace the signal plate. 9. CHECK INTERMITTENT INCIDENT Refer to EC-147, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" . >> INSPECTION END Component Inspection UBS002UJ CRANKSHAFT POSITION SENSOR (POS) 1. Loosen the fixing bolt of the sensor. 2. Disconnect crankshaft position sensor (POS) harness connector. 3. Remove the sensor. 4. Visually check the sensor for chipping.

All codes are OBDll and are available on line free. they do not pinpoint a specific part. Take car to repair shop, it will much cheaper in the long run. do you have a complete set of tools. a garage to work in, time, skill set

Who replaced the sensor ? You or a repair shop ? The DTC P0336 does not say to replace a sensor . You do not have access to the diagnostic trouble code diagnostic's . Your best bet ,take it to a qualified repair shop .
DTC P0336: Crankshaft Position (CKP) Sensor Performance
CKP Sensor Signal Circuit
P0335
P0335
P0335
P0336

P0336
• The ECM detects that the engine is running, but receives less than 51 or more than 65 CKP sensor pulses each engine revolution for 8 of 10 engine revolutions.
• The ECM detects that the engine is running, but more than 19 resyncs occur within 25 seconds.
• The ECM detects that the engine has been running, but the crankshaft does not sync for 0.4 second.

P0335 - Crankshaft Position Sensor 'A' Circuit Malfunction

Possible causes- Faulty crankshaft position sensor (most common)
- Crankshaft position sensor harness is open or shorted
- Crankshaft position sensor circuit poor electrical connection
- Signal plate may be damage
- Starter motor may be faulty
- Starting system circuit
- Dead or weak battery causing slow engine crank over.

Let's start with the codes.

Po129 refers to barosensor

Po344 is a code for the camshaft position sensor

Po339 crankshaft position sensor

Po340 camshaft position circuit malfunction

Po335 crankshaft POS sensor malfunction

Po122 throttle pedal position

Item 2,3,4,5 relate to each other that s camshaft and crankshaft position sensors. Since both already show a malfunction code, it would be advisable to change.

Sometimes other codes show up because there is a relation but not that the item is bad.

This could be related to a loose camshaft drive belt. If you have slack in the belt the camshaft will rebound on over run causing the P0340. It can also be a Crackshaft sensor problem too.(P0335) Hope this helps...

Diagnostic Trouble Code (DTC) P0335

Magnetic Crankshaft Position Sensor Electrical Error

In this circuit DTC (data trouble code) sets when

a) The magnetic crankshaft position sensor is > 0.2V.

Or when

b) The minimum value of magnetic crankshaft position sensor is

Or when

c) The maximum value of magnetic crankshaft position sensor is higher than 2.2V.

P0335 - Crankshaft Position Sensor "A" Circuit
P0342 - Camshaft Position Sensor "A" Circuit Low Bank 1 or Single Sensor.

In the kit there are two sensor that look identical. The one for the crankshaft has a white paint mark on it near the bolt hole. Make sure that it is in the right location.
