HINT:

Read freeze frame data using an intelligent tester. Freeze frame data record the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data, from the time the malfunction occurred.

INSPECT CAMSHAFT POSITION SENSOR (RESISTANCE)

(a) Disconnect the C1 Camshaft Position (CMP) sensor connector.

(b) Measure the resistance between terminals 1 and 2. Standard Resistance

Tester Connections

Specified Conditions

1 - 2

835 to 1,400 n at cold

1 - 2

1,060 to 1,645 n at hot

HINT:

Terms cold and hot refer to the temperature of the coils. Cold means approximately -10° to 50°C (l4° to 122°F). Hot means approximately 50° to 100°C (122° to 212°F). (c) Reconnect the CMP sensor connector.

REPLACE CAMSHAFT POSITION SENSOR

CHECK HARNESS AND CONNECTOR (CAMSHAFT POSITION SENSOR - ECM)

Wire Harness Side:

CMP Sensor Connector

(a) Disconnect the C1 CMP sensor connector.

(b) Disconnect the E4 ECM connector.

(c) Check the resistance.
