im stumped. I have actually a inspect engine irradiate on and also i cant figure it out. The van is an 85 ramcharger with a 1994 360 magnum. I confirm the password 5 or 6 times and they every come up the same. 34, 53, 13, 73, 2, 55. On line i read that all of the codes that have to come out have to be 2 number codes. The truck runs great, no lacking or sputtering and all the power is there. I simply dont desire to get stranded if there in reality is a problem... Any aid is considerably appriciated

Its no hooked up best now. I"m not actual worried about that code, I"m an ext worried about the 53 code... It runs simply fine, think it will provide me problems on a much longer drive?

Its no hooked up appropriate now. I"m not real worried about that code, I"m more worried around the 53 code... It runs just fine, think that will provide me problems on a longer drive?
I cant say for sure, it could be that your computer system is some just how tripping out and giving friend a code like code 13...The engine computer system is yes, really nothing an ext that a large grounding block, v PNP and NPN transistors...

The reasonable modules provides this details to control the field present in the alternator. This code applies ONLY come alternators who voltage is computer system regulated. If you lose the feeding to keep RAM information stored as soon as the engine"s off, you also lose battery voltage sensing. -- Bohdan BodnarNOTE #2.From the 1995 van manuals: the trailer towing package consists of a infection coolant temp sensor while the traditional package doesn"t. This may cause the short (no) voltage indication. -- J.E. WinburnNOTE #3.Matt Rowe comments: The accelerator postion circuit speak the computer system how far the accelerator is depressed. The Throttle position Sensor (TPS) is on the accelerator body ~ above the opposite next of the accelerator cable. The connector should have a round rubber cover end the connections. Clean the error codes, start the vehicle and shot jiggling the wires/connectors to shot to expedition a fault code. Loss of this signal could cause other problems.NOTE #4.During cranking, the computer system will check the current through the injector to check out whether there"s too much resistance in the injector"s path. If over there is, password 26 is set.The problem may be cured with tuner cleaner on the connectors.For TBI engines, the injector"s cold resistance must be in between 0.9 and 1.2 ohms (specs vary through year). This is a peak-and-hold injector. Through the engine idling the peak period should be about 1.2 millisecond whereas the hold period will vary. If it"s reduced than this in ~ idle, climate the injector"s shorted or there"s a defect in the injector driver circuit. (Bohdan Bodnar)NOTE #5.Wade Goldman wrote: In mine case, the breather pipe leading right into the catalytic converter had actually rusted and also become detached. This some how would cause the sensor to review an over affluent condition and run crummy. Ns did not trust the reliability of the weld end a corroded surface and opted because that the an ext expensive course of replacing the converter, breather tube and also all.NOTE #6.The Z1 voltage is the voltage that the circuits fed by the autoshutdown relay. This frequently includes fuel pump and also switched-battery feed to the ignition coil(s). In my Le Baron, the Z1 circuit pipeline the power module and also splits into two paths: the fuel pump and also the positive side that the ignition coil. Inner to the power module is the auto shutdown relay (in my case, it"s a sealed box around 1" by 1"). The calculation voltage is monitored to determine whether the relay responds correctly. I doubt that the ASD relay (and, therefore, the Z1 circuit) additionally feeds the fuel injector(s) driver(s) and also current sensing circuit, however can"t prove this.I"ve supplied the Z1 voltage to test for great power relations to the strength module. I linked my OTC 500 multimeter indigenous the battery"s positive write-up to the ignition coil"s switched battery terminal and also measured the voltage drop utilizing the bar graph come monitor optimal voltages. Voltage spikes of roughly 200 mV to 300 mV are ok -- noþeles more method tv tuner cleaner time (or replacing the strength module). Another thing to check is the best voltage drop throughout the priming pulse. V the old strength module, ns was losing around 2 volts throughout the circuit; the instead of is losing around 1/4 volt.

If you look in ~ the four slotted tangs within there girlfriend will watch one has actually a bigger slot, that"s the one the tells the sync pickup what"s number one. In various other words, the pickup within the distributor is bad.
