Engine Stalls

Engine Starts And Then Stalls

• On Avalon, Camry, Camry Solara, Celica, Corolla, ECHO, Highlander, Matrix, MR2, Prius, RAV4, Sienna, Tacoma, Tundra 3.4L V6 and 4Runner, check fuel pump control circuit. See FUEL PUMP CONTROL CIRCUIT under COMPUTERIZED ENGINE CONTROLS in appropriate SYSTEM & COMPONENT TESTING article.
• On MR2 with sequential manual transaxle, check throttle body and components for Electronic Throttle Control System (ETCS). See THROTTLE BODY under IDLE CONTROL SYSTEMS in SYSTEM & COMPONENT TESTING - 4-CYLINDER article. Models with sequential manual transaxle may be identified by the shift lever pattern which consists of "R", "N", "S" and "+" in place of the conventional type shift lever pattern and no clutch pedal is used.
• On Land Cruiser, Sequoia and Tundra 4.7L V8, check fuel pump control circuit. See DTC P0230: FUEL PUMP PRIMARY CIRCUIT under DIAGNIOSTIC TESTS in appropriate SELF-DIAGNOSTICS article.

Engine Stall After Accelerator Pedal Depressed (MR2 & RAV4)

• On Camry (except Solara), Corolla, Matrix, MR2 and RAV4 models, check injector circuit. See DTC P0300: RANDOM/MULTIPLE CYLINDER MISFIRE DETECTED under DIAGNOSTIC TESTS in appropriate SELF-DIAGNOSTICS article.
• On MR2 with sequential manual transaxle, check throttle body and components for Electronic Throttle Control System (ETCS). See THROTTLE BODY under IDLE CONTROL SYSTEMS in SYSTEM & COMPONENT TESTING - 4-CYLINDER article. Models with sequential manual transaxle may be identified by the shift lever pattern which consists of "R", "N", "S" and "+" in place of the conventional type shift lever pattern and no clutch pedal is used.
• On Corolla and Matrix, check ISC valve circuit. See DTC P0505: IDLE CONTROL SYSTEM MALFUNCTION under DIAGNOSTIC TESTS in SELF DIAGNOSTICS - COROLLA & MATRIX article.
• On MR2 (with standard M/T), check IAC valve circuit. See DTC P0505 & P0511: IDLE AIR CONTROL MALFUNCTION under DIAGNOSTIC TESTS in SELF DIAGNOSTICS - MR2 article.
• On RAV4, check IAC valve circuit. See DTC P0505: IDLE CONTROL SYSTEM MALFUNCTION under DIAGNOSTIC TESTS in SELF DIAGNOSTICS - RAV4 article.
• Check Engine Control Module (ECM) power source and backup power source circuit. See ENGINE CONTROL MODULE POWER SOURCE CIRCUIT under COMPUTERIZED ENGINE CONTROLS in appropriate SYSTEM & COMPONENT TESTING article and DTC P0560: SYSTEM VOLTAGE under DIAGNOSTIC TESTS in appropriate SELF-DIAGNOSTICS article.

Engine Stall After Accelerator Pedal Released (Corolla, Matrix, MR2 & RAV4)

• Check Engine Control Module (ECM) power source and backup power source circuit. See ENGINE CONTROL MODULE POWER SOURCE CIRCUIT under COMPUTERIZED ENGINE CONTROLS in appropriate SYSTEM & COMPONENT TESTING article and DTC P0560: SYSTEM VOLTAGE under DIAGNOSTIC TESTS in appropriate SELF-DIAGNOSTICS article.
• On MR2 with sequential manual transaxle, check throttle body and components for Electronic Throttle Control System (ETCS). See THROTTLE BODY under IDLE CONTROL SYSTEMS in SYSTEM & COMPONENT TESTING - 4-CYLINDER article. Models with sequential manual transaxle may be identified by the shift lever pattern which consists of "R", "N", "S" and "+" in place of the conventional type shift lever pattern and no clutch pedal is used.
• On Corolla and Matrix, check ISC valve circuit. See DTC P0505: IDLE CONTROL SYSTEM MALFUNCTION under DIAGNOSTIC TESTS in SELF DIAGNOSTICS - COROLLA & MATRIX article.
• On MR2 (with standard M/T), check IAC valve circuit. See DTC P0505 & P0511: IDLE AIR CONTROL MALFUNCTION under DIAGNOSTIC TESTS in SELF DIAGNOSTICS - MR2 article.
• On RAV4, check IAC valve circuit. See DTC P0505: IDLE CONTROL SYSTEM MALFUNCTION under DIAGNOSTIC TESTS in SELF DIAGNOSTICS - RAV4 article.

Engine Stall During A/C Operation

• Check A/C signal. A/C signal may also be referred to as A/C switch signal or compressor circuit. See appropriate MANUAL or AUTOMATIC A/C-HEATER SYSTEMS article in AIR CONDITIONING & HEATING.
• Check Engine Control Module (ECM) power source and backup power source circuit. See ENGINE CONTROL MODULE POWER SOURCE CIRCUIT under COMPUTERIZED ENGINE CONTROLS in appropriate SYSTEM & COMPONENT TESTING article and DTC P0560: SYSTEM VOLTAGE under DIAGNOSTIC TESTS in appropriate SELF-DIAGNOSTICS article.
