What to do if there is no throttle response?
What to do if there is no throttle response?
0V If voltage is >0.039V, check ground circuit for resistance >5 . breakout box to determine if resistance is in the harness. Replace the sensor if the code is active and the expected results are obtained with all the sensor tests. The sensor is not at fault if one or more of the sensor tests does not produce the expected results.
Why is my ISC motor not responding to my PCM?
If the wiring harness appears to be good, and the ISC solenoid or motor is receiving a signal from the PCM — but is not responding — you can assume the fault is a bad ISC motor or solenoid. Unfortunately, some technicians just replace the ISC motor or solenoid before checking these other possibilities, and then discover it didn’t fix the fault.
When does the idle validation switch receive a signal?
The ECM expects to receive one of two signals through the ECM chassis connector (black) terminal 27 from APS/IVS connector terminal D: 0V when the pedal is at the idle position. 12V when the pedal is depressed. The Idle Validation Switch receives 12V ignition voltage from the ignition fuse in the fuse box.
What happens if throttle is not applied at Terminal 8?
If the APS signal at terminal 8 indicates throttle is being applied, the ECM expects to see 12V at IVS terminal 27. If the APS signal at terminal 8 indicates throttle is not applied, the ECM expects to see 0V at IVS terminal 27. The timing process is critical between the APS and IVS sensors.

When does the idle validation switch receive 12V?
0V when the pedal is at the idle position. 12V when the pedal is depressed. The Idle Validation Switch receives 12V ignition voltage from the ignition fuse in the fuse box. When the pedal is NOT in the idle position (throttle applied), the IVS supplies a 12V signal to the ECM.
Is there a problem with the throttle pedal?
The engine starts fine the problem is that throttle pedal doesn’t accelerate some time and some times just disappear at the time i am driving. Went to several shops they replace censor, problem disappear for one week and then come back again.
Is there a throttle response on an IH 4300?
No throttle response every once in a while. Turn the key off and everything is ok. 2004 IH 4300 1HTMMAAN24H609204 4H609204 I erased them but the twin to this truck had these codes with a similar problem. PID 91 FMI 7, PID 102 FMI 2, SID 230 FMI 2
