1JZ ECU Code 47: Sub-Throttle position sensor

[EvilJack]

Hey all, i bought a SARD JZX90 ecu and when hooked up i am getting error code 47 which is open or short in circuit of sub-throttle position circuit.

Off the conditions that JZZ30 and JZX90 ECU's are the same (currently run a JZZ30 ecu) i figured it would be a direct replacement.

I run the non TRC throttle body which doesnt have the sub-throttle position sensor and has been fine on the JZZ30 ecu.

Im wondering if anyone else has come across this error and whether the JZZ30 and JZX90 TRC setup is wired differently?

I was going to open the ECU to check the capacitors etc but want to try and avoid damaging the genuine analyse sealed stickers.

Any ideas would be appreciated

Cheers
Andrew

It would have been tuned to suit a jzx90 with TRC thats all. some jzz30,s had TRC and some didnt , Id say its the same for the jzx 90 , if you want the code gone just wire up the VCC pin to the VTA pin for the sub throttle sensor . Giving it a wide open signal
