Hitachi TPS0006 Throttle Position Sensor

I own a 2000 Nissan Xterra, who back in November of 2020 had an entire transmission rebuild. Fast-forward to December of 2021 and I notice it feels like he's not shifting correctly, hesitating on acceleration, and frequently idling so rough he seems like he's going to stall out. I of course assume the worst and plan to take him in to have that transmission looked at again. But since I didn't need the Xterra as a daily driver I just parked him and avoided thinking about the possible issues till a couple months ago.Luckily, my dad got to talking with his brother who suggested to first check if the TPS was working right. Turns out that's what was going out. This TPS is fully OEM, identical to the factory one we removed from him. It arrived incredibly quickly, was a very easy swap out, and so far has fixed the issue entirely. A+ quality, and I highly suggest it.

Removed the old one, fitted and calibrated this new one, reset the idle memory and ECU, and back on the road with a properly running motor, in less than 45 mins.Excellent OEM replacement. Works exactly as it should.If you ever get sent an obviously used item, return it to the vendor and insist on a new one.

Great product, same as original

TPS replacement fixed P0120 DTC that had my 1999 Nissan Pathfinder R50 automatic in Fail Safe Mode.Swapped out the old unit, installed and calibrated the new one, reset idle memory, and road-tested in well under an hour. Result: Smooth idle, acceleration, and shifting, all restored!This TPS is an exact Hitachi factory original for my Pathfinder, but at a fraction of the price the local Nissan dealer charges. Shipping from the US to Colombia took just 5 days.

I purchased this for $46 in May, 2014. Installed on a 2000 Xterra. Works perfectly. 10 min install included adjustment. Shipping was about $8 and arrived reasonably fast via FedEx. Good unit.

After trying a SCITOO brand generic replacement, this HITACHI is a perfect fit. It was very easy to install and make minor adjustments. The SCITOO brand was so tight making the necessary adjustments was very difficult.

OEM for 2004 Nissan Xterra XE v6 4x4 even though Amazon says it won't fit. This is a direct replacement.Background for the diy'ers:Months leading to failure, throttle would randomly stick, then stutter before RPM's would kick up, but no CEL (check engine light).Gas mileage had been horrendous leading up to this point. No store codes or other indicator of problem.While idling at lights, truck would randomly surge RPMs. Again, no stored codes.Driving slowly down road, CEL tripped and held following codes: P0733, P0734, P0121. P0733 and P0734 are related to transmission. P0121 is related to this sensor.Ordered this part, and installed trying to adjust as well as a novice could. Immediately after CEL tripped and P0122 code stored. Now transmission is slipping between 2-3 and initial idle is high till it warms and drops to targeted 750 rpm's. Wasn't sure if bad luck in two parts possibly failing at same time with transmission or related to this sensor as it sends signals to ECM on when to shift. Was hoping for sensor, since transmission was fine immediately before, but in the back of my head, P0733/P0734 did also trip.Brought to dealer, thinking they'd give the Xterra it's last rites; however, once TPS was properly installed, all problems cleared immediately, including transmission slipping. It's only been a few days, but surging RPMs seemed to have ceased, which was a problem leading up to the P0121 code.Bottom-line, pretty important part that interfaces with the ECM/Transmission.Hope this helps someone.

I thought we were looking at an in-depth transmission repair as the Batmobile was exhibiting some erratic down-shifting as well as hard or abnormal up-shifts to the extent of appearing to be slipping at times. Untimed downshifts while on the interstate were driving me insane. Another symptom was erratic idling and poor pick-up. This had been going on for a few months and steadily getting worse. The only 2 trouble codes coughed up by the ECM pertained to the knock sensor and an O2 sensor, that's all. From the moment I started driving after replacing the TPS (by the way, this TPS is the exact one that comes on this 1999.5 QX4 from the factory in Japan), all of the abovementioned issues ceased to exist. Every single one! Wow! If you have any of these symptoms on your QX4/Pathfinder, don't overlook the possibility that it may be your TPS. But, if you have to replace it, don't settle for anything less than this Hitachi TPS. I will be well worth a few extra bucks. Signed...Trina's husband.
