Hello,
I have a question about my 2001 US/CDA spec Suzuki Esteem with the J18 MPFI engine.
The TPS has not been moved and is adjusted to the 0.5V factory value.
With an OBD2 scanner hooked up, the live data TPS % parameter shows 0.0% whenever the car is coasting in gear, or during warm idle. Is this a normal condition? On my other Suzuki product (G10 SOHC TBI) the OBD scanner reports around 10% TPS % at warm idle. Is this because the ISC motor actually moves the throttle plate, whereas the MPFI J18 engine uses the IAC to provide idle air while the throttle plate remains absolutely closed?
