hey guys i got a 94 accord ex with the check engine light on i jumped the blue harness and turned on my ignition to start..... 8 short flashes pause then 2 long flashes pause and then 1 short flash. after this it takes a long pause and starts all over again. so im reading 29 but i cant find no codes with that number. can anybody help me find out wat it is. my car is manual transmission and is running fine. thanks

 

Here's the flash code list; code 8 might be the first thing to check out.

Honda Codes p
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
71 random misfire cylinder 1
72 random misfire cylinder 2
73 random misfire cylinder 3
74 random misfire cylinder 4

 

Sounds like a code 8 and 21

 

ya your right my friend works at honda he said 8 and 21 top dead sensor and vtech spool solenoid valve this is my first honda so all this is new to me how hard is all this to do guys

 

The TDC is part of the distributor. You can test the resistance on that sensor to see if it has gone bad. You can also inspect the wiring.

You would likely have to replace the distributor if the sensor is bad. Its a pretty easy DIY.

The vtec spool solenoid is on the cylinder head. You should test the resistance as stated in the shop manual.

Download the 94 shop manual from the spooner tuner site referenced in Online manuals thread in the DIY section.
