1996 Toyota Camry Q&A
1996 Toyota Camry Question: I can't get my check engine light to go off and stay off
I took the motor from my 96 2.2L automatic and put it in my 96 standard car. This car has less factory electronics under the hood, therefore some of the vacuums are different. I have two vacumms pluged off now. The check engine light stays on w/wo them plugged off. The code for oxygen/ fuel mixture regulator comes up. But, this car doesn't have the elec. Plug for that device. - lusenut75
There are some things today that you just shouldn't do IMO and less than exact matching engine swaps is one of them. At this point you need to retrieve the code and troubleshoot it exactly as required. Being a 96 both were OBDII so if you are setting O2 sensor codes, then you have to restore the circuit so that the computer is happy with it. As far as the light simply going off it doesn't always work that way, in fact it usually doesn't just go right off when a circuit is restored. You can try to clear the code and see if it stays off, but if it comes back right away you have a hard failure on the circuit. Post the code and we can tell you where to start for the diagnostics but the fun has really just begun here. Because of the systems dependency on inputs, codes not only indicate a problem they prevent related tests from running and so you often fix one problem only to have the light come on again shortly thereafter, with a completely different code set. In the past people would think that you did something wrong, or made the problem occur somehow when the reality is there usually is no way to know about any additional issues until the vehicle completes all of its testing. In your case you have even added a variable which really can't be accounted for (the engine mismatch). - cardocIII
One question, was the light on before the engine swap? You should have all of the necessary componets to repair this! - pushrod
Swapped harness and PCMs? - ziptie12
I get an intermittant engine code (about once a week but sometimes more often) that is P0401 - EGR Low Flow. The first think I did was to warm up the engine, then with a finger touching the EGR dia...
Am getting the engine light about once a week (I reset it - it will stay off a while then come back on). It always reports P0401 Low EGR flow. This is the Japam made camry for those that know the d...
At first it would just come on when I started my car up and turn off after about a mile. However now it comes on and will stay on for 20 minutes, every now and they it will just go on and off at ra...
