Sensor location??????

[demarpaint]

Thanks in advance,

I have an older 4.9L 1988 E-150 van. I would like to know where the ECT and ACT sensors are located. I think the ECT is located in the thermostat housing? Not sure where the ACT is.

Please advise,

Thanks

Does ACT mean air temp sensor?

ACT= Air Charge Temperature Sensor

Thanks

I have a Haynes here for that van (I've got an '87 inline 6) but it doesn't use the same terms. Is this a sensor for a trap door in the airbox?

Going by my book (never have replaced one on a 4.9 myself), it is on the #1 lower intake runner, looks to be behind the alternator.
