Honda Element. Manual - part 89

Fig. 252: Throttle Position (TP) Sensor Circuit Diagram 

General Description 

The engine control module (ECM)/powertrain control module (PCM) uses the serial signal line for two-way 
communication with the throttle actuator control module. 

The ECM/PCM transmits the accelerator pedal position signal to the throttle actuator module, and the throttle 
actuator control module transmits the actual throttle valve position signal, or a malfunction signal, etc., to the

ECM/PCM via this line. 

When no serial signals from the throttle actuator control module are received or the serial signals are abnormal 
for more than a set time, the ECM/PCM detects a malfunction and a DTC is stored.

MONITOR DESCRIPTION 

Enable Conditions 

ENABLE CONDITIONS 

Malfunction Threshold 

One of these conditions must be met for at least 0.25 second. 



No serial signals from the throttle actuator control module are detected.  



The serial signals from the throttle actuator control module are abnormal.  

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.

DTC U0122: F-CAN MALFUNCTION (VSA-ECM/PCM)

Fig. 253: Communication Diagram Between ECM/PCM And Control Module 

General Description 

The controller area network (CAN) transmits/receives pulsing signals to/from the control modules 
simultaneously by using two signal lines (CANH and CANL). 

When the engine control module (ECM)/powertrain control module (PCM) does not receive the signals via the 
CAN lines for more than a set time, the ECM/PCM detects a malfunction and a DTC is stored.

DTC U0155: F-CAN MALFUNCTION (GAUGE CONTROL MODULE-ENGINE CONTROL 
MODULE (ECM)/POWERTRAIN CONTROL MODULE (PCM)) 

Fig. 254: Communication Diagram Between ECM/PCM And Gauge Control Module 

General Description 

The controller area network (CAN) transmits/receives pulsing signals to/from the control modules 
simultaneously by using two signal lines (CANH and CANL). 

When the engine control module (ECM)/powertrain control module (PCM) does not receive the signals from 
the gauge control module via the CAN lines for more than a set time, the ECM/PCM detects a malfunction and 
a DTC is stored.
