Ok so or 98 v6 camaro with lik180,000miles,check engine light came on, and i went down to the the auto zone and had them check it for me and here are the codes ithad.p0113,p0507,p0102.

can you guys tell me what these mean and what needs to be fixed,so we can fix it.

Thanks Tony.

 

P 0102 MAF shows no air flow while engine running. Check for air leak downstream of MAF, causing it to be bypassed
DIAGNOSTIC AIDS
Inspect for the following conditions:[*]A misrouted harness-Inspect the harness of the MAF sensor in order to verify that it is not routed too close to the following components:[*]The secondary ignition wires or coils[*]Any solenoids[*]Any relays[*]Any motors[*]A low minimum air rate through the sensor bore may cause this DTC to set at idle or during deceleration. Inspect for any vacuum leaks downstream of the MAF sensor.[*]Check for restricted intake, dirty MAF, dirty air cleaner.[*]A resistance of 20 ohms or more on the ground circuit of the MAF sensor can cause this DTC to set.

P 0113 IAT (Incoming Air Temp sensor) shows incoming air as being at -38 degrees F (Do you live in Siberia ?) lol
DIAGNOSTIC AIDS[*]When the vehicle is at ambient temperature the IAT sensor and ECT sensor temperatures should be relatively close to each other. Refer to Temperature vs Resistance. Check IAT temp with scanner & compare to coolant temp)[*]If a short to a separate 5-volt source occurs this DTC may set. If this condition exists, a continuity test to all other PCM 5-volt reference circuits will be necessary.[*]IAT sensor disconnected

P 0507 Idle speeed is too high. TAC (Throttle ACtuator)not able to bring idle to proper RPM

DIAGNOSTIC AIDS
Check for vacuum/air leaks downstream of MAF
Check for vacuum/air leaks Downstrem of throttle valve
Check for bad PCV valve
Dirty or binding throttle valve

SWAG: Clean out the air intake sytem, Air filter, MAF, Throttle body, PCV
