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.

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

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.
