1. DTC P0335 description
The CKP sensor is installed on the top of the flywheel housing. There are 56 notches spaced 6° apart and a 30° opening on the outer circumference of the flywheel. Top dead center of cylinder No. 1 can be detected through this opening. The CKP sensor is a magnetic resistance element type sensor, and generates a square wave signal pulse. The sensor has the following circuits.
- 5 V reference circuit
- Low reference circuit
- CKP sensor signal circuit
The ECM monitors the signal pulses of the CKP sensor and the CMP sensor to make sure they correlate with each other. If the ECM receives a certain amount of CMP sensor signal pulses with no CKP sensor signal pulses detected, the DTC is set.

2. Condition for setting DTC P0335
Condition for running the DTC
- The battery voltage is 9 to 16 V.
- The ignition voltage is 9 to 16 V.
- The ignition switch is ON.
- The CMP sensor signal pulses are detected.
- DTCs P0336 and P0340 are not set.
Refer to "51.Engine Control 1A.Troubleshooting(RZ4E-TC) DTC P0340 (Flash Code 14) Camshaft Position Sensor Circuit".
Condition for setting the DTC
- The ECM detects that no CKP sensor signal pulse is generated while the engine is running.
3. Action taken when DTC P0335 sets
- Euro4: The ECM illuminates the MIL. Refer to Action taken when DTC sets - Type A (Euro4).
- Except Euro4: The ECM illuminates the check engine warning light. Refer to Action taken when DTC sets - Type A (Except Euro4).
Refer to "51.Engine Control 1A.Troubleshooting(RZ4E-TC) DTC type definitions".
- The ECM limits the fuel rail pressure.
- The ECM inhibits the cruise control.
4. Condition for clearing DTC P0335
- Euro4: Refer to Condition for clearing the MIL/DTC - Type A or Type B (Euro4).
- Except Euro4: Refer to Condition for clearing the check engine warning light/DTC - Type A or Type B (Except Euro4).
Refer to "51.Engine Control 1A.Troubleshooting(RZ4E-TC) DTC type definitions".
