BH:DTC P0196 ENGINE OIL TEMPERATURE SENSOR CIRCUIT RANGE/PER-
FORMANCE
1. OUTLINE OF DIAGNOSIS
Detect for abnormal values in the oil temperature sensor output properties.
Judge as NG when the oil temperature does not rise even though the engine is running under a condition
where it should rise.
2. ENABLE CONDITIONS
3. GENERAL DRIVING CYCLE
Perform the diagnosis continuously after starting the engine.
4. DIAGNOSTIC METHOD
Abnormality Judgment
When the following conditions are established, it is NG.
After engine start oil temperature sensor characteristic diagnosis timer (timer for diagnosis).

Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
Leak Diagnosis
DTC
P0442 Evaporative Emission Control System Leak Detected (Small Leak)
P0457 Evaporative Emission Control System Leak Detected (Fuel Cap Loose/Off)
Diagnostic method
The diagnostic method consists of creating a sealed vacuum in the fuel tank and then determining the pres-
ence of leakage from the speed at which the tank internal pressure returns to atmospheric pressure.
Mode A: (Estimated evaporation gas amount)
Calculate the tank pressure change amount (P1) when using mode A. After calculating P1, switch to mode B.
Mode B: (Negative pressure sealed)
Introduce negative pressure in the intake manifold to the tank.
Approx. 0 → –1.4 (0 → –10.5, 0 → –0.41) kPa (mmHg, inHg)
When the pressure above (desired negative pressure) is reached, enters Mode C.
In this case, if the tank pressure does not become the desired negative pressure, judge that there is a large
leakage (10 seconds or 25 seconds) in the system.
Abnormality Judgment
Judge as NG (large leak) when the criteria below are met.
Mode C: (Check pressure rise)
Stop the introduction of negative pressure. (Wait until the tank pressure returns to the start level of P2 cal-
culation.)
Change to Mode D when the tank pressure returns to the start level of P2 calculation.
Judge immediate OK and change to Mode E when it does not return in spite of spending the specified time.
Mode D: (Measure amount of negative pressure change)
Monitor the tank pressure change amount when using mode D. In this case, the tank pressure increases,
(nears atmospheric pressure) because evaporation occurs. However, if any leakage exists, the pressure in-
creases additionally in proportion to this leakage. The pressure variation of this tank is P2.
After calculating P2, perform a small leak diagnosis according to the items below.
When Mode D is ended
Assign tank variations measured in Mode A and Mode B; P1 and P2, to the formula below, judge small leaks
in the system. If the measured judgment value exceeds the threshold value, it is judged to be a malfunction.
Judge as NG when the criteria below are completed and Judge as OK when not completed.

DTC
P0456 Evaporative Emission Control System Leak Detected (very small leak)
Diagnostic method
The diagnostic method consists of creating a sealed vacuum in the fuel tank and then determining the pres-
ence of leakage from the speed at which the tank internal pressure returns to atmospheric pressure.
Mode A: (0 Point Compensation)
When pressure in tank is high, wait for 0 point 0 kPa (Near 0 mmHg, 0 inHg) to return.Shift to mode B when
0 point returns.
Cancel the diagnosis when 0 point does not return in the specified time.
Mode B: (Negative pressure introduced)
Introduce negative pressure in the intake manifold to the tank.
Approx. 0 → –2.0 kPa (0 mmHg → –15 mmHg, 0 → –0.59 inHg)
When the pressure above (desired negative pressure) is reached, Mode C is entered.
Cancel the diagnosis when the targeted pressure in the tank is not reached.
Mode C: (Negative pressure maintained)
Stop the introduction of negative pressure and wait until the tank pressure returns to the start level of P2 cal-
culation.
Change to Mode D either when the tank pressure returns to the start level of P2 calculation, or when the pre-
determined amount of time has passed.
Mode D: (Calculate the amount of negative pressure change)
Monitor the tank pressure in mode D, calculate (P2) the pressure change in the tank, and measure the time
(evpdset) for the tank pressure to return when calculation of P2 is completed. Shift to mode E when pressure
returns. Make an advance OK judgment using the value of P2, or cancel, when the pressure in the tank does
not return after calculation of P2 is completed even when the predetermined amount of time has passed.
When the following conditions are established, it is OK.

engine oil level is below “L” line, add oil to bring the
level up to “F” line.
5) After turning off the engine, wait a few minutes
for the oil to return to the oil pan before checking
the level.

5) Using engine oil of proper quality and viscosity,
fill engine oil through the oil filler duct to the upper
level on level gauge. Make sure that the vehicle is
parked on a level surface when checking oil level.
Recommended oil:
Refer to “SPECIFICATION” for the recom-
mended oil. CATION, General Description.>
