an actual throttle valve position signal.

If the signal from TP sensor B is a fixed value or less for a set time, the throttle actuator control module detects
a malfunction and sends the malfunction data to the ECM/PCM. When the ECM/PCM receives the malfunction
data from the throttle actuator control module, the ECM/PCM detects a TP sensor B malfunction and stores a
DTC.

MONITOR DESCRIPTION

Enable Conditions

ENABLE CONDITIONS

Malfunction Threshold

The TP sensor B output voltage is 0.3 V or less for at least 0.2 second.

Diagnosis Details

Conditions for illuminating the MIL

When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the
ECM/PCM memory.

Conditions for clearing the MIL

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic
runs.

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by
disconnecting the battery.

Fig. 40: Throttle Position (TP) Sensor Circuit Diagram

General Description

Throttle position (TP) sensor B is a semiconductor type, and it is attached to the throttle body and shaft to
determine throttle valve position.

The throttle valve position signal from TP sensor B is transmitted to the throttle actuator control module for
target position feedback control, then to the engine control module (ECM)/powertrain control module (PCM) as

If the signal from TP sensor B is a fixed value or more for a set time, the throttle actuator control module
detects a malfunction and sends the malfunction data to the ECM/PCM. When the ECM/PCM receives the
malfunction data from the throttle actuator control module, the ECM/PCM detects a TP sensor B malfunction
and stores a DTC.

Fig. 41: Crankshaft Position Sensor Pulse Data

General Description

The crankshaft vibrates slightly when each cylinder fires. If a misfire occurs, the crankshaft rotation speed
changes rapidly. The engine control module (ECM)/powertrain control module (PCM) monitors the crankshaft
rotation speed based on the output pulses from the crankshaft position (CKP) sensor. By monitoring changes in
the crankshaft rotation speed, the ECM/PCM counts the number of misfires and determines which cylinder is
misfiring. If more than one DTC from P0301 through P0304 has been stored while misfires in multiple
cylinders are detected, a malfunction is detected and a DTC is stored.

There are two types of misfire detection.

Type 1 (1 drive cycle): When the number of misfires per 200 engine revolutions reaches the level that damages
the three way catalyst (TWC), a DTC is stored and the MIL blinks. When the misfire ceases, the MIL remains
on steady instead of blinking.

Type 2 (2 drive cycles): When the number of misfires per 1,000 engine revolutions reaches the level that affects
FTP mode exhaust emissions, a DTC is stored and the MIL comes on.
