P1190 - Intake Throttle Actuator Malfunction
P1190 Possible Causes
- Faulty Throttle Solenoid Valve
- Throttle Solenoid Valve harness is open or shorted
- Throttle Solenoid Valve circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How is the P1190 code repair?Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
What is the cost to diagnose the P1190 code
Labor: 1.0The cost to diagnose the P1190 code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.

P1190 Meaningy actuating of flaps in the intake passage the passage at the inlet valve of the cylinder can be narrowed. This reduces the air flow. The flaps in the intake passage are controlled by the intake throttle actuator. Calculation of the duty cycle for the inlet passage shut-off can be switched on and off by the function switch of the inlet passage shut off. If the engine speed and the demand quantity + low idle governor exceed certain thresholds, also the MAFS signal must be above a threshold. If this not the case, the error "flap blocked closed" is recognized. If the engine speed and the control duty cycle exceed certain thresholds, the digital switch of the inlet passage shut off must be actuated. If it is, the error flap blocked open is recognized. In case of the throttle actuator stuck, the engine symptoms will occur a running engine stall and a starting impossible.
