DTC P0335: Crankshaft Position Sensor "A" Circuit (FROM 12/2010); DTC P0339: Crankshaft Position Sensor "A" Circuit Intermittent (FROM 12/2010): Procedure

WARNING: This page is about a different car, the 2011 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.

INSPECT CRANKSHAFT POSITION SENSOR

Disconnect the crankshaft position (CKP) sensor connector.

Measure the resistance according to the value(s) in the table below.

Standard resistance

Tester Connection	Condition	Specified Condition
1 - 2	Cold	1630 to 2740 Ω
1 - 2	Hot	2065 to 3225 Ω

HINT:

Terms "cold" and "hot" refer to the temperature of the coils. "Cold" means approximately -10 to 50°C (14 to 122°F). "Hot" means approximately 50 to 100°C (122 to 212°F).

Reconnect the CKP sensor connector.

NG → See step 5

OK: Go to next step

CHECK HARNESS AND CONNECTOR (CRANKSHAFT POSITION SENSOR - ECM)

Disconnect the CKP sensor connector.
Disconnect the ECM connector.

Measure the resistance according to the value(s) in the table below.

Standard resistance (Check for open)

Tester Connection	Condition	Specified Condition
B7-1 - B50-110 (NE+)	Always	Below 1 Ω
B7-2 - B50-111 (NE-)	Always	Below 1 Ω

Standard resistance (Check for short)

Tester Connection	Condition	Specified Condition
B7-1 or B50-110 (NE+) - Body ground	Always	10 kΩ or higher
B7-2 or B50-111 (NE-) - Body ground	Always	10 kΩ or higher

Reconnect the ECM connector.
Reconnect the CKP sensor connector.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR

OK: Go to next step

CHECK SENSOR INSTALLATION (CRANKSHAFT POSITION SENSOR)
1. Check the CKP sensor installation condition.

  OK
  
  Sensor is installed correctly.
NG → See step 6

OK: Go to next step
CHECK CRANKSHAFT POSITION SENSOR PLATE (TEETH OF SENSOR PLATE)
1. Check the teeth of the sensor plate.
  OK
  
  Sensor plate does not have any cracks or deformation.
NG → See step 7

OK → See step 8
REPLACE CRANKSHAFT POSITION SENSOR. Refer to REMOVAL
REPLACE CRANKSHAFT POSITION SENSOR. Refer to REMOVAL
REPLACE CRANKSHAFT. Refer to DISASSEMBLY
REPLACE ECM. Refer to REMOVAL
