What does P0737 Mean? Is the fuel pump sometimes not priming when you turn the key to ON(II)? Start by measuring the fuel pressure and checking whether you have bright white-bluish spark at all four plugs. The mechanical timing is also something that you should check, as we mentioned above. When you see P0737 engine fault code on your engine code reader this description will help you. engine code P0737P0737 fixobd P0737dtc P0737obd code P0737obd2 P0737P0737 car codediagnostic code P0737car code P0737check engine code P0737fehlercode P0737P0737 fiatcodigo P0737codigo falla P0737P0737 kody b??dówcodigo de falla P0737 What are the common causes of P0737 ? The most common causes of this code being stored are due to a defective engine output speed sensor or transmission output speed sensor. Other common causes include shorted, open, corroded, or damaged wiring circuits or connectors, faulty shift solenoid/s, defective engine drivability sensors (especially the engine temperature sensor), dirty or contaminated transmission fluid that restricts flow, defective valve body, a faulty PCM. PCM failure is rare. How do you troubleshoot P0737 ? With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground. If all testing has passed so far yet you still have the same code, check your scan tool and see if it can open and close the IMRC valve. If the engine displays a miss and there wasn't a code, determine which cylinder is misfiring. If the exhaust manifold is visible, spay or pour a small amount of water on each cylinder exhaust port. Water will evaporate immediately on good cylinders and slowly on the missing cylinder. If this can't be accomplished pull the plugs and check the condition.
