DTC |
P050B00 |
Cold Start Ignition Timing Performance |
MONITOR DESCRIPTION
A monitor will run when the engine is started at an engine coolant temperature of -10 to 50°C (14 to 122°F). If certain conditions are met, a DTC is stored after the engine idles for 13 seconds (2 trip detection logic).
This DTC is designed to monitor the ignition timing at cold start. When the engine is started at an engine coolant temperature of less than 50°C (122°F), the ECM checks the ignition timing during engine idling. If the ignition timing advances beyond the specified level within 10 seconds, the ECM interprets this as a malfunction, illuminates the MIL and stores this DTC.
NOTICE:
The idle speed control learned values are cleared by performing learning value reset. Idle speed control learning needs to be performed before this DTC can be stored.
HINT:
Idle speed control learning is performed when the engine is warmed up and has been idling for 5 minutes.

CONFIRMATION DRIVING PATTERN
HINT:
-
After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

-
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for at least 30 seconds.
- Start the engine and warm it up for 5 minutes or more.
- Stop the engine.
- Leave the vehicle outside overnight.
- Turn the ignition switch to ON [A].
- Turn the Techstream on.
- Enter the following menus: Powertrain / Engine / Data List / Coolant Temperature.
- Check that the value of the Data List item Coolant Temperature is between -10 and 50°C (14 and 122°F).
- Start the engine and warm it up until the engine coolant temperature is the same as the coolant temperature in the Freeze Frame Data.
- Idle the engine for 1 minute or more [B].
- Enter the following menus: Powertrain / Engine / Trouble Codes [C].
-

CAUTION / NOTICE / HINT
NOTICE:
Inspect the fuses for circuits related to this system before performing the following procedure.
HINT:
-
DTC P050B00 may be set when the engine has the symptoms listed below. If necessary, check the trouble areas listed below.
Symptoms
Factor
Trouble Area
Low idle speed when engine is cold
(immediately after engine start)
Excessive engine friction
- Engine oil deterioration
- Drive belt tension
- A/C compressor
- Generator assembly
Rough idle when engine is cold
(immediately after engine start)
