Honda Element. Manual - part 6

When the change in coolant temperature after 10 minutes or more of running time is 50 °F (10 °C) or less, a 
malfunction is detected. 

Malfunction determination 2: 

With a partially cooled engine (one that has been off for less than 6 hours): 

When the difference between the coolant temperature after 10 minutes or more of running time minus the 
coolant temperature after the engine has been off for 150 minutes and then run for 10 seconds is 50 °F (10 °C) 
or less, a malfunction is detected. 

Driving Pattern 



With a completely cooled engine (one that has been off for at least 6 hours).  

1. Start the engine, and let it idle for at least 10 minutes.  

2. Turn off the ignition for 10 seconds, then restart the engine and let it idle for at least 10 seconds. 



With a partially cooled engine (one that has been off for less than 6 hours).  

1. Start the engine, and let it idle for at least 10 minutes.  

2. Turn off the ignition for 150 minutes, then restart the engine and let it idle for at least 10 seconds.  

Diagnosis Details 

Conditions for illuminating the MIL 

When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the ECM/PCM 
memory. If the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and the 
freeze frame data are stored. 

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

DTC P0117 (6): ADVANCED DIAGNOSTICS 

DTC P0117: ENGINE COOLANT TEMPERATURE (ECT) SENSOR 1 CIRCUIT LOW VOLTAGE

General Description 

Engine coolant temperature (ECT) sensor 1 is used for air/fuel ratio feedback control, ignition timing control, 
idle speed control, and other functions. The ECT sensor 1 resistance varies depending on the engine coolant 
temperature. As the engine coolant cools, the ECT sensor 1 resistance increases, and the engine control module 
(ECM)/powertrain control module (PCM) detects a high signal voltage. As the engine coolant warms, the ECT 
sensor 1 resistance decreases, and the ECM/PCM detects a low signal voltage. If the ECT sensor 1 output 
voltage is less than a set value when the engine coolant temperature is high, the ECM/PCM detects a 
malfunction and a DTC is stored.
