DTC P1603-00: Engine Stall History [12/2019 - 10/2022]: Procedure

1. Enter the following menus: Powertrain / Engine / Trouble Codes.
2. Read the DTCs.

   Powertrain > Engine > Trouble Codes 

   Result

   Result	Proceed to
   Only DTC P1603-00 is output	A
   DTCs other than P1603-00 are output	B

   HINT: 

   • When DTC P1603-00 and P1605-00 are output simultaneously, perform the troubleshooting for P1605-00 first.
   • Using Freeze Frame Data, confirm the conditions the moment the DTC was stored and after the DTC was stored. This information can be useful when troubleshooting.

Result: 

B 

GO TO DTC CHART. Refer to  DIAGNOSTIC TROUBLE CODE CHART [12/2019 - 09/2020]  , or refer to  DIAGNOSTIC TROUBLE CODE CHART [09/2020 - 10/2021]  , or refer to  DIAGNOSTIC TROUBLE CODE CHART [10/2021 - 10/2022] 

Result: 

A 

See step  2

1. Using the GTS, confirm the vehicle conditions recorded in the Freeze Frame Data which were present when the DTC was stored.

   Powertrain > Engine > DTC (P1603-00) > Freeze Frame Data 

   Tester Display
   ISC F/B Learn Torque

   Result

   Freeze Frame Data Item for DTC P1603-00	Result	Suspected Area	Action	Proceed to
   ISC F/B Learn Torque	Less than 30 Nm	-	Go to the next step	A
   	30 Nm or higher	Throttle body with motor assembly	Go to ENGINE STALLS (from step 11)	B

Result: 

B 

GO TO ENGINE STALLS. Refer to  Engine Stalls [12/2019 - 10/2022] 

Result: 

A 

See step  3

1. Using the GTS, confirm the vehicle conditions recorded in the Freeze Frame Data which were present when the DTC was stored.

   Powertrain > Engine > DTC (P1603-00) > Freeze Frame Data 

   Tester Display
   A/F (O2) Sensor Voltage B1S1
   A/F (O2) Sensor Voltage B2S1
   Short FT B1S1
   Short FT B2S1
   Long FT B1S1
   Long FT B2S1

   Result

   Freeze Frame Data Item for DTC P1603-00			Suspected Area	Action	Proceed to
   A/F (O2) Sensor Voltage B1S1 and A/F (O2) Sensor Voltage B2S1	Short FT B1S1 and Short FT B2S1	Long FT B1S1 and Long FT B2S1
   2.8 V to 3.8 V	-15% to 15%	-15% to 15%	-	Go to ENGINE STALLS	NEXT
   3.8 V or higher	15% or higher	-	Fuel pump	Go to ENGINE STALLS (from step 20)
   Less than 2.8 V, or 3.8 V or higher	Less than -15%, or 15% or higher	Less than -15%, or 15% or higher	Mass air flow meter sub-assembly Air fuel ratio sensor Fuel pump	Go to ENGINE STALLS (from step 15)*

   HINT: 

   *: If the value of A/F (O2) Sensor Voltage B1S1, A/F (O2) Sensor Voltage B2S1, Short FT B1S1, Short FT B2S1, Long FT B1S1 or Long FT B2S1 is as specified, malfunction of a component listed in the "Suspected Area" column of the table is suspected.
