code 3

[civicHBsi91]

im getting a code 3 absolute manifold pressure, can anyone help me with this? i feel dumb asking this question i know i seen this question before but i searched and came up with nothing, help is appreciated

Code #3: Most likely an electrical problem in the MAP sensor
Start engine & warm to operating temp & check MAP sensor connections
Pull hazard fuse from under hood
Re-install fuse
Start engine & check for re-coding

It could be a wiring problem, bad map sensor, or bad ECU.

i have a feeling its the ecu, i dunno when it happends theres a funky ass smell, oh well i got me a new job that pays good, might just convert to obd1.....

do like jackass said, pull the hazard fuse for 10 sec and warm the engien back up and see if it still throws the code, make sure the cooling fan comes on to let u know its all warmed up.

if u still get the code, turn the car off and pull the connector from the map snesor and turn the igniton on, measure the voltage between the yell/red and the ground, there should be 5volts. if there is 5 volts then measure the volts between the yel/red and grn/wht, there should be 5 volts. if there is 5 volts then measure the voltage between the white and grn/wht wires, there should be 5 volts. if there is 5 volts turn the ignition off and reconnect the connector. then turn the ignition back on and check the voltage between c11 and c14 on the ecu, there should be 3volts, reminder that the ecu needs to be hooked up so go fromt eh wiring harness side to measure. if there isnt 3 volts replace the map sensor, if there is get a good ecu

that should take care of it. if any of the steps before the ecu fail, then theres an open circuit somewhere, let me know what happens so i can tell u exactly to where the opne circuit goes to on the ecu
