Yeah CODES! facetious sarcasm - Beastcub - 10-06-2021 Ok, 1994 Suzuki Sidekick JLX. (4 door, 4wd, auto, federal emissions). Finally after that nag debacle I got the diagnostic to run and got code 34 MAF (16valve only) Air Flow Sensor Circuit ,too low current. , lower than 0.65mA detected. So Im going to try and clean it with MAF cleaner. If that doesnt work what else should I try before buying a new sensor? ANd If I have to buy a new sensor which one do you guys recommend (not a lot of choices) It has 229000 miles on it and runs good.

Finally after that nag debacle I got the diagnostic to run and gotgreat nag is gone, now you can work on it easy not worry that. yes the MAF first see if the thing is plugged in, sure it is. then make sure it has legit MAF p/n on the side and if missing is a crap china MAF that are useless (ebay $15 mafs are) 13800-58B00 (USA only) is this, hot wire used in USA. clones have no suz. number, best rebuilt is Cardone, look for sales googling is best. using the cardone numbers. off there web site. CARDONE does not do direct sales, so google it. wires at plug not damaged or pins bad looking unplugged. and then the voltmeter test https://fixkick.com/sensors/92-95MAF/92-95-MAF-testing.html keyon only volts =1.0–1.6 volts (zero air flow voltage is this idle voltage is 1.7–2.0 volts. at 800 RPM gun throttle might see 3v my SHOP VAC sucking hard key on gets 3.0vdc. out. (huge shop vac with 2" hose. if have an excel plot and my jpg echo of same here. that far reach only happens at 95 HP real . if maf is bad you can never see 95HP ever. ![]() long ago the MAf WAS $1200 @suzuki dealers So I was motivated to measure it all ways possible. yes clean the hot wire, be 6"or more inches away from wire, and clean it 3 times soak it 1min and repeat, few times. freeway driving in heavy traffic can coke it up bad. good luck to you ! and cHeers/ RE: Yeah CODES! facetious sarcasm - fixkick - 10-06-2021 ecu reports only dead maf not weak . explained the ECU uses the MAF for all fuel mix calcultation it also watches (DTC monitors live) f for stuck high and dead and stuck low and dead. both will set the 2 matching DTC codes. example, 1: if the maf should read say 3v at 70 hp engine power but is 2v you do not get that power level (it goes lean) but the ECU simply likes that wrong 2vdc level it is happy as a clam. (but not us ever) 'see? RE: Yeah CODES! facetious sarcasm - Beastcub - 10-07-2021 what do you mean "ecu reports only dead maf not weak" ? ARe you saying getting a code 34 means that the MAF is not dead? I dont have much history with this truck. Ive had it a year and got it from my ex brother in law (he was going to junk it, running and driving). I havent been driving it Ive just been fixing it up RE: Yeah CODES! facetious sarcasm - fixkick - 10-07-2021 (10-07-2021, 05:52 AM)Beastcub Wrote: what do you mean "ecu reports only dead maf not weak" ?

I havent been driving it Ive just been fixing it upOBD1 is not smart at all like modern cars the errors mean dead. this Car does not report weak sensor, as all modern obd2 cars do 1996 and newer, that code means the maf is dead. OBD1 only does things see on my page the checks are outputs stuck high or stuck a zero. DTCs are from catastrophic tests that run full time, 51 is special. if sensor shorts to ground it fails if it short to 5v or 12 vdc it show stuck high. and both mean dead. code 51 can be , and mean weak that is one exception. weak EGR flow, it can detect. https://fixkick.com/ECU/DTC-errors/DTC-jtgh.html Battlefield™ 2042 Battlefiehttps://fixkick.com/ECU/DTC-errors/DTC-jtgh.htmlld™ 2042 RE: Yeah CODES! facetious sarcasm - fixkick - 10-07-2021 now what new cars do ,MAF wise if weak the ecu knows that due to having on board a MAF simulator that (uses RPM , TPS throttle angle, RPM and what gear) and if this simulator shows way off VALUE from MAF readings, it sets a weak MAF error, ... or shows this, TPS(etc) is non congruent to maf.) modern OBD2,. The maf dead on your car forces, LIMPHOME MODE, (gee still runs ) it run only because of the below. this mode is a MAF emulator but is super super inaccurate, and runs rich a hell even 15mpg bad. some folks are happy in limphome , one guy here only uses the car to pull stumps and is happy, even with spark plugs fouling all the time. if the ECU did not have limphome mode, a dead maf kills injection dead. (no GO) this is why LIMPhome exists , only that, car still moves. (like magic) true name is failsafe, but limphome limp are common jargon now on modern cars. RE: Yeah CODES! facetious sarcasm - fixkick - 10-07-2021 now a 1060s answer a CARB car or motor cycle. main jet clogs 1/2 way, and a huge lack of power from engine, (lean) so I grab my choke knob, and add just enough choke to get full power, so the makes me the human limp mode man. see? done it vast times.

Yeah most of my cars are OBD I or no computer ( 84 Laser XE, 86 EXP, 94 Sidekick, 89 Mark VII, 78 Mark V, 70 Mustang, 72 Stingray, 81 Honda Civic, 1936 Cord 810, then 98 Mercury Grand Marquis, 2020 Volvo S60 T8 Polestar, and 2021 Lexus LC500 convert.) and diagnosing OBD1 or finding someone who remembers or knows is a PAIN! so THANK YOU for your help. That being said I found MAF from SKP, WalkerProducts, Cardone, Delphi, Beck/Arnley and WVE. The tag on my sensor is 13800-58B00 (next line) E5T53071 4509. Ive heard of Cardone ( I sold auto parts for years, Napa, Advance, Pep Boys, AZ) which Ive had issues with and BECK and Delphi.. Any suggestions??

Any suggestions?? even used if it is promised by seller (ebay) as no DOA warranty. down time can be very important to you. I guess your maf is dead (volt text x2 tells that easy. if dead try to find spare that is used or rebuilt. with that number on the side 13800-58B00 (next line) E5T53071 4509.this is ALL 100% suzuki coes, and the e number is makers number to suzuki. the clones have no number at all or odd has heck. cardone as you know is huge top USA rebuilder. for MAF AND ECU ON THIS CAR. NOT MANY OF these cars running now so no rebuilder wants to sell things for this car . So what youre telliing me is I need a new MAF sensor. LOL no, I was only saying to test it, I'd not say it's bad lacking test data. (Volt meter) needle probe backprobing it finds this. not me. good luck fiix this car and there are very very few OBD2 cars on the road, now. well except your COLLECTION... I am glad to help you, I still remember it all , , even after being retired for 10 years. The ECu trusts all outputs from the ECU blind unless those 2 dead code DTC 33/34 hit and goes to limphome mode. |
