Hey guys, my check engine is on for some reason, my swap is complete my ecu is chipped to my engine needs, but that light stays on, does anyone know why? could it be because i have a catback exhaust system with high flow cat? or is there a sensor o something im missing?
 
have you bridged the connecters to find out what code is throwing?
 
go into the footwell where the ecu is. the will be two blue plugs. one thats got two wires and one thats got three. get the one with the two and either get a paperclip or a bit of wire and put each bit in the connecter holes so the signal is getting sent back. you engine light will flash. count the flashes a long flash is ten and short is one. then ther will be a pause if there is more than one code it will starts flashing again if not it will just flash the same ammoun as the first time . heres what the codes mean 1 O2A - Oxygen sensor #1
2 O2B - Oxygen sensor #2
3 MAP - manifold absolute pressure sensor
4 CKP - crank position sensor
5 MAP - manifold absolute pressure sensor
6 ECT - water temperature sensor
7 TPS - throttle position sensor
8 TDC - top dead centre sensor
9 CYP - cylinder sensor
10 IAT - intake air temperature sensor
12 EGR - exhaust gas recirculation lift valve
13 BARO - atmospheric pressure sensor
14 IAC (EACV) - idle air control valve
15 Ignition output signal
16 Fuel injectors
17 VSS - speed sensor
19 Automatic transmission lockup control valve
20 Electrical load detector
21 VTEC spool solenoid valve
22 VTEC pressure valve
23 Knock sensor
30 Automatic transmission A signal
31 Automatic transmission B signal
36 traction control found on JDM ecu's
41 Primary oxygen sensor heater
43 Fuel supply system
45 Fuel system too rich or lean
48 LAF - lean air fuel sensor
54 CKF - crank fluctuation sensor
58 TDC sensor #2
61 Primary oxygen sensor
63 Secondary oxygen sensor
65 Secondary oxygen sensor heater
67 Catalyst low efficiency. (same as P0420)
71 random misfire cylinder 1
72 random misfire cylinder 2
73 random misfire cylinder 3
74 random misfire cylinder 4
80 Exhaust Gas Recirculation insufficient flow detected
86 ECT Sensor (Engine Coolant Temperature) circuit range / performance problem
90 Evaporative Emission Control System leak detected in the fuel tank area
91 Evaporative Emission Control System insufficient purge flow
 
Im getting a engine code "13" atmospheric pressure sensor, where is this located?, and what does it do to the engines performance:)
please help
