Multiple Sensor Questions

[Jorge - 98 Disc]

Hello,
I just purchased a code reader I got:
P0110 Intake Air Temperature Sensor 1 Circuit
P0100 Mass or Volume air flow circuit
P1600 Unable to find details for this code
P0120 throttle/pedal position sensor a circuit
P0115 engine coolant tempurature circuit

Now it seems I have issure swith the MAF, air charge sensor and engine coolant sensor and a throttle censor, is there something I can do to clean them? What am I looking at as far as cost to replace these sensors? Any help as to where I can purchase? thank you all in advance.

If you've got a bunch (over 150k) mi, I suppose the 110,115,120 sensors could be bad, but I'd start by cleaning the MAF, then clearing the codes.

I have used MAF cleaner(spray), electronic spray, (no residue) & it worked well.

I'd strongly recommemd to NOT spray parts when hot/warn as the spray is cold.

I just saturate the part and roll it around to drain.

Check/clean your connections to the other sensors, too.

If you have the rave cd, it's got the test values in it.

luck,greg
