I have a 1994 HH4 Acty van. 90,000 kms on it. It’s fuel injected. I got it in Florida where it was warm, and then drove it 600 miles home with no problems. The very next day, it was below freezing, and the check engine light came on (after the van warmed up.) I turned the ignition off and on and it went away. Now, I’ve driven it for 3000 kms, and every random 300-600 kms it will come on again, and then go away if I restart the car. I’ve noticed it happens whenever I’m in 4th or 5th gear and am coasting while still in gear. I’m thinking it might not like the cold weather, but I’m not sure. Any ideas? Also, how do I get the code for the check engine light? It doesn’t have an obdII port, so I’m lost.
Honda-and-Acura-OBD1-Trouble-codes-How-to-read-and-what-they-mean How to Read the Code In OBD1 Hondas and Acuras there is a diagnostic port and a two-pin connector located under the passenger-side dashboard. When checking the DTCs you will need to insert a jumper wire from one pin to the other in the two-pin connector. If you don't have a piece of wire around, it is also common to see people using paperclips to "jump" the two sides of the connector. Once you have "jumped" the two-pin connector, you now need to insert the key and turn on the vehicle. Your check engine light will then start to flash. Every long flash is a digit in the "tens" place in the code, and a short flash is a digit in the "ones" place. So, if you see two long flashes and five short flashes, you have a Code 25. There will be a long pause between codes. Read all the codes until they start to repeat themselves. Then refer to the table below to get the meaning of each code. Codes 0 and 11 Electronic control module (ECM) Code 1 Heated oxygen sensor A Code 2 Oxygen content B Codes 3 and 5 Manifold absolute pressure Code 4 Crank position sensor Code 6 Engine coolant temperature Code 7 Throttle position sensor Code 8 Top dead center sensor Code 9 No.1 cylinder position sensor Code 10 Intake air temperature sensor Code 12 Exhaust recirculation system Code 13 Barometric pressure sensor Code 14 Idle air control valve or bad ECM Code 15 Ignition output signal Code 16 Fuel Injector Code 17 Vehicle speed sensor Code 19 A/T lock-up control solenoid Code 20 Electric load detector Code 21 V-TEC control solenoid Code 22 V-TEC pressure solenoid Code 23 Knock sensor Code 30 A/T FI signal A Code 30 A/T FI signal B Code 41 Heated oxygen sensor heater Code 43 Fuel supply system Code 45 Fuel supply metering Code 48 Heated oxygen sensor Code 61 Front heated oxygen sensor Code 63 Rear heated oxygen sensor Code 65 Rear heated oxygen sensor heater Code 67 Catalytic converter system Code 70 Automatic transaxle Code 71 Misfire detected cylinder 1 Code 72 Misfire detected cylinder 2 Code 73 Misfire detected cylinder 3 Code 74 Misfire detected cylinder 4 Code 75 Misfire detected cylinder 5 Code 76 Misfire detected cylinder 6 Code 80 Exhaust recirculation system Code 86 Coolant temperature Code 92 Evaporative emission control system https://axleaddict.com/auto-repair/Honda-and-Acura-OBD1-Trouble-codes-How-to-read-and-what-they-mean Try that, maybe it works. I never tried that
Thanks, I'll give it a try! I'm thinking it won't come up though because once I turn the key on and off it goes away. But worth a shot! Kind of related: do you know where the battery is on the HH4 vans? I can't find it at all!
Van I had to search, on the truck it is easy to find, here is a lot of info for the truck and that also helps you for the van, what is where https://robrobinette.com/Honda_ACTY.htm Here is a van owners manual/handbook in Japanese , see page 183 of 238 https://www.onlymanuals.com/manuals/cars/honda/other_model/honda_auto_honda_acty_van_2001_73969 open the hood, should be next to left front wheel, also see page 220
