INSPECTION PROCEDURE
HINT:
Read freeze frame data usingthe hand−held tester. Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was
running or stopped, 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.
1CHECK FUSE(THROTTLE FUSE)
(a) Remove the THROTTLE fuse from the engine room R/B
No.1.
(b) Check for continuity in the THROTTLE fuse.
Standard: Continuity
(c) Reinstall the THROTTLE fuse.

DTC P0617 STARTER RELAY CIRCUIT HIGH
CIRCUIT DESCRIPTION
While the engine is being cranked, the positive battery voltage is applied to terminal STA of the ECM.
If the vehicle is being driven and the ECM detects the starter control signal (STA), the ECM concludes that
the starter control circuit is malfunctioning. The ECM will turn on the CHK ENG and a DTC is set.

sor heater circuit uses a relay on the B+ side of the circuit.

MONITOR DESCRIPTION
The inner surface of the A/F sensor element is exposed to outside air. The outer surface of the sensor ele-
ment is exposed to exhaust gases. The sensor element is made of platinum coated zirconia and includes
an integrated heating element. The zirconia element generates small voltage when there is a large differ-
ence in the oxygen concentrations of the exhaust and the outside air. The platinum coating amplifies the
voltage generation. When heated, the sensor becomes very efficient. If the temperature of the exhaust is
low, the sensor will not generate useful voltage signals without supplemental heating. The ECM regulates
the supplemental heating using a duty−cycle approach to regulate the average current in the heater ele-
ment. If the heater current is out of the normal range, the sensor’s output signals will be inaccurate and the
ECM can not regulate the air−fuel ratio properly. When the heater current is out of the normal operating
range, the ECM interprets this as a malfunction and sets a DTC.
